0.20-1

	[NEW] {CoordinateAxis} Axes now carry their own units for parsing
	and formatting.

	[NEW] Common Data interface for handling multidimensional data.

	[NEW] New 1D image classes (Data1D, Samples1D, Overlay1D...), which
	act similarly to their 2D counterparts.

	[NEW] New 3D and 2D+1D image classes that act similarly to their
	2D counterparts.

	[NEW] Coordinate2D.convertFrom()/To().

	[NEW] Parallel now has synchronize() method to provide common 
	synchronization points among the worker threads.

	[FIX] {DoubleFFT} {FloatFFT} Fixed amplitude normalization of Nyquist-
	unrolled real transforms.

	[FIX] {MultiFFT} Fixes to multidimensional FFT 

	[FIX] {FFT} NyquistUnrolled amplitude scaling now applies to unrolled
	Nyquist component also.

	[FIX] {FFT} Fixed amplitude normalization for NyquistUnrolled real 
	transforms.

	[FIX] A bunch of potential bugs found and fixed with the help of
	FindBugs.

	[FIX] Reinstated standard long FITS header keywords. Problems occur
	only when trimming comments...

	[FIX] More fixes to home-brewed long FITS header cards.

	[FIX] Flawed implementation of equals() for many of the classes.
	Classes that derived directly from Object should not rely on
	super.equals() typically, as it will return false always, unless
	the two objects are one and the same.

	[CHANGE] {FFT} FFTs now work with oversized arrays, setting 
	untransformed trailing elements to NaN or null, as appropriate.

	[CHANGE] Complete overhaul of 2D image classes and related classes,
	with the aim of more versatile, more powerful and cleaner code, that
	is easier to maintain.

	[TWEAK] {FFT} FFTs now clear away leftover input data when processing
	oversized arrays.

	[TWEAK] SphericalCoordinates now have default coordinate systems that
	format coordinates in DMS or HMS formats, and offsets in arcseconds 
	with 3 decimals, by default.

	[TWEAK] {SphericalCoordinates} Parsing now recognizes 2-letter codes
	in front of coordinates and will attempt an appropriate conversion if
	possible (or throw an exception if not...)

	[TWEAK] {CubicSpline} Streamlined spline calculation slightly.

	[TWEAK] {FFT} Parallel FFTs migrated to use Parallel for threading.
	Some simplifications (especially MultiFFT) and cleanup.

	[FIX] {AngleFormat} Better rounding for formatted output, plus much 
	improved parsing of various angle formats...

	[FIX] More consistent and robust parsing of 2D coordinates from text.

	[FIX] {CubicSpline} was not properly initialized, returning NaN
	when evaluated at 0 first. Fixed.

	[FIX] {CubicSpline} Poorly handled negative indices due to simple
	modulus (%) operator. Not a big issue since negative indices weren't
	really used. Fixed anyway...

	[FIX] {Data2D} mean() was not actually a weighted mean.

	[CODE] More potential bugs found and fixed with the help of Eclipse.
	(e.g. null pointers, hidden variables). Streamlined to avoud
	unnecessary casts, tailored clone() return types, unnecessary else
	statements.

	[CODE] Grids read/write FITS headers using the axis units.

	[CODE] Lots of tweaks to Grid classes. More generalized hierarchy.

	[CODE] Vector2D, Vector3D, RealVector and GenericVetor classes now
	use common superinterfaces that provide interoperability.


0.11-3

	[FIX] Fixed constructor of CompoundUnit(String).

	[TWEAK] ExponentUnit recognises both "**" and "^" as exponent markers
	by default.


0.11-2

	[CODE] Data2D.fwhm2size moved to Constant.
	
	[CODE] Data2D.getHistogram() refactored to more universal 
	Histogram.createFrom(Object data).


0.11-1


	[NEW] {Configurator} methods for processing environment-based and 
	Java property-based conditionals.

	[NEW] {CircularRegion+} possibility of reporting properties to FITS 
	header.

	[FIX] {Configurator} 'relock' was not working.

	[FIX] {Broadcaster} Concurrency issue with Broadcaster if new message 
	is created while reporting another one. Fixed.

	[FIX] {Parallel} Parallel processing errors during init(), or cleanup()
	were uncaught and could result in hangs. Now, these are reported as 
	proper parallel exceptions, just the those produced by the main body. 
	If multiple exceptions occur (e.g. both during processing and cleanup),
	only the first one encountered will be reported.

	[TWEAK] {ConsoleReporter} Console reporting of details now has space 
	between leading '...' and message for cleaner visual appearance.

	[UPDATE] Leap seconds updated to latest -- now 37 seconds...

	[CODE] MatrixIterator class is hidden (private subclass of
	AbstractMatrix).

	[CODE] Reorganization: jnum.data.mesh.* --> jnum.data.*
	
	[CODE] Reorganization: Matrixes and related classes moved to new
	jnum.math.matrix package,

	[CODE] Multidimensional arrays (Mesh and subclasses) are taking shape
	(more or less)...

	[CODE] TableFormatter simplified generation of entries and toplevel
	formatting.

	[COPYRIGHT] Fixed stale reference to kovacs.util in copyright notices
	in all source files.


0.10-1


	[BUG] {CircularRegion} isInside() methods treated radii as pixels not 
	angle.

	[BUG] Handling of empty ranges (inclusion, restriction, or intersection
	checking) was crazy bad. Fixed.
	
	[NEW] Range2D class.

	[NEW] TextWrapper class to aid wrapping texts, with a bunch of useful 
	add-on features (line headers, indentation after first line, justified
	output).

	[NEW] SmartTokenizer class (based on StringTokenizer) to simplify 
	parsing tokenized values.

	[NEW] LineParser class to uniformize the reading of text input files.
	 
	[NEW] Util class now contains a default Reporter for conveying JNUM
	messages. Few jnum classes use it at this point, but the plan is that
	they will all use it in the future to communicate messages to the user. 

	[FIX] {Region} Integrated fluxes were calculated in enclosing box, not 
	strictly the region itself.

	[FIX] {FITS} Long HISTORY entries ended up producing corrupted FITS
        files (due to a bug in the nom.tam.fits libraries). A workaround has
        been added to break long history entries into multiple lines. Wrapped
        lines start with "... " for easier human recognition...

	[CHANGE] {Data2D} The 2D data classes (Data2D and derivatives) now
	report through the default reporter of the Util class. 


0.09-2

	[BUG] ArrayUtil.copy() misbehaved (hung) when trying to copy 
	heterogeneous arrays. Fixed.

	[NEW] Brand new jnum.data.fitting API. Includes fixes to covariance
	calculation. Allows for restricted parameter ranges, and formulating
	fitting constraints.

	[NEW] Added expm1() and log1p() functions for Complex numbers.

	[FIX] {FFT} Recalculation of twiddle factors when skipping over data
	blocks is made safer for multithreading.

	[FIX] {ExtraMath} Fixes to various long integer functions.
	
	[FIX] {Data2D} autocrop to check for and avoid null ranges.

	[CHANGE] {ExtraMath} updated integer functions log2XXX() and pow2XXX()
	with faster methods using builtin integer methods.

	[CHANGE] {Data2D} Added LONGSTRN keyword to properly identify the
	convention used to store long FITS header entries. It is set to
	'OGIP 1.0' by default, when long strings are enabled in the FITS libs.
	Otherwise it's set to 'CRUSH' if and when CRUSH's own convention is
	used instead.

	[CHANGE] {FitsExtras} Long FITS header entries are now written using 
	the default FITS long strings convention by default (with CONTINUE 
	keys). However, the parsing of long keys will continue to recognise 
	CRUSH's own convention for legacy.

	[TWEAK] Improved address bit counting, based on builtin functions. 
	And safer bitshift-down operations with '>>>' instead of '>>'.

	[COSMETIC] {SignificantFigures} Formating of zero values without 
	exponent.


0.09-1

	[NEW] New class Angle for faster rotations of Vector2D (or Complex 
	numbers), using precalculated sin and cos terms.

	[NEW] Parser for enclosed expressions (EnclosureParser). E.g. 
	for expressions enclosed in brackets (BracketParser) or in quotes
	(QuoteParser).

	[NEW] Additional classes Brackets, QuotationMarks, Subscript and
	SuperScript for looking up common unicode symbols.

	[NEW] Offset2D to represent an offset from a particular 2D coordinate.
	The subclass Projected2D can be used to bundle offsets with the 
	particular projection as well.

	[NEW] TelescopeCoordinates for representing native telescope 
	coordinates in cross-elevation and elevation. (Uses FITS WCS naming
	TLON/TLAT).

	[NEW] Improved flag management.

	[NEW] Introducing the ability to lock, unlock and relock configuration 
	settings, e.g. to prevent changes to these later (e.g. by 
	conditionals). 

	[NEW] Improved polling of settings via the '-poll' command. Apart from
        listing current settings for all keys that start with the specified
        pattern (as it used to), it now also list any matching settings that
        were blacklisted (as bracketed). And, it also lists any conditions
        that might change a matching settings conditionally.

	[FIX] LocalAverage indexBefore() lookup could be off by a little
	since the step size was not forced to be a power of 2. Fixed.

	[FIX] SphericalProjection FITS header comment was identical for both
	axes. Fixed.

	[FITS] The nom.tam.fits package updated to the official 1.14.2
	release.

	[CODE] Conversion from median variance to sigma^2 is now a constant
	in Statistics.

	[CODE] {CoordinateAxis} Improved labelling by allowing long, short and
	fancy labels. For example the equatorial RA direction might have a long
	descriptive label, such as "Right Ascension", a short text label "RA"
	and a fancy (non-ASCII) label with the unicode greek letter alpha.

	[CODE] {Symbol} Added a bunch of unicode characters to Symbol 
	(especially common math and physics related ones).

	[CODE] Plugges some potential resource leaks.

	[CODE] Changed how blacklisted settings are handled by the 
	Configurator. The new approach is cleaner, and faster, and is a step
	towards allowing locking settings in their state also. More changes 
	will follow...

	[CODE] Many classes now implement Serializable, and also override
	hashCode() and equals() more consisitently.

	[CODE] nom.tam.fits libraries upgraded to ver. 1.13.1.


0.08-1

	[NEW] {Data2D} Parse and write back existing history entries.

	[NEW] Additional merging and flagging convenience methods added to
	Data2D (and derivatives).

	[NEW] Static createArray(size) methods added to WeightedPoint, 
	DataPoint, Vector2D, Complex -- aiding the array creation of these.

	[FIX] parsing of coordinate pair produced error if only a single 
	character followed the comma separator.

	[FIX] Empty ranges returned -Infinity spans. Fixed.

	[TWEAK] Data2D use of executor still uses the requested number of
	parallel threads only.

	[TWEAK] editHeader(Cursor) -> editHeader(Header, Cursor) allowing more
	access to existing keys.

	[TWEAK] Parallel to optionally process through ExecutorService.

	[TWEAK] 'Doppler' colorscheme slightly altered to dim on both ends.
	This makes for a visually more pleasant range...


0.07-1 (16 June 2015)
	

	[BUG] Aperture flux uncertainties in prior release were garabage.
	Fixed. 

	[BUG] {AstroTime} FITS timestamping time part malformed in previous
	release. Fixed. 

	[FIX] {Configurator} Condition value checking [key?value] made case 
	insensitive (i.e. the match to 'value' is case independent).

	[TWEAK] {GridMap} Smarter reading of FITS images into weighted maps.
	If it has multiple HDUs, the noise and coverage information is 
	collected from any HDUs with meaningful labels (EXTNAME header key).
	If the FITS does not contain additional HDUs, or none that are suitable
	for determining weight or coverage (even in a rudimentary way), then
	uniform weights are assumed.

	[TWEAK] {ExponentUnit} Negative exponents bracketed by '(' and ')',
	following the FITS standard, rather than '{' and '}' before.

	[TWEAK] {Unit} Added some more unit names to lookup for acceptable
	FITS aliases. E.g., see: 
	  https://astropy.readthedocs.org/en/v0.1/wcs/units.html

	[CODE] {MultiFFT} Use ExtraMath.roundupRation where possible.


0.06-1 (31 March 2015)


	[NEW] Added units for speed [kmh], [mph], and knots [kn, kt, kts], 
	and nautical mile [nmi, NM, M].

	[NEW] SafeMath class for asin(), acos() and sqrt() to return normal
	values when rounding errors could push the argument outside of the
	strict domain. The tolerated level of rounding error should accomodate
	a good deal of float-precision calculations (on the order of a few 
	thousand compounded rounding errors).
	
	[NEW] {FitsExtras} Ability to parse units from comment or header values 
	whose unit appears in the comment. The comment is parsed for the 
	unit specification according to the following priorities:

		1. the value inside the first square brackets, e.g. '[arcsec]'
		2. the value inside the first brackets, e.g. '(arcsec)'
		3. the first word of the comment. E.g. "arcsec blah-blah..."

	[NEW] {GridImage} Updated to use proper Gaussian beams (see more 
	below).
	
	[NEW] {GridImage} keeps track of the underlying FWHM (such as an 
	instrument beam).

	[NEW] GaussianPSF class for handling elongated Gaussian beams, in 
	general.

	[FIX] {Grid2D} parsing of reverted coordinate axes did not invert
	sign of transformation terms as expected. (Grid2D is defined on native
	coordinates, whereas FITS headers are written in apparent coordinates). 

	[FIX] Many fixes to AstroTime: more precise GMST and LMST calculations.
	Improved FITS timestamping of integer MJD dates. Timestamping always
	based on UTC otherwise.
	
	[FIX] {SphericalGrid} non-default constructor did not properly 
	initialize before.

	[TWEAK] {CoordinateAxis} wcsName removed. Its function is overtaken
	by SphericalCoordinates.getFITSLongitudeStem() and 
	getFITSLatitudeStem().

	[TWEAK] {Grid2D} Removed hard units (degrees). Non-default Units are 
	properly parsed from, and written to, the FITS headers.

	[TWEAK] {CoordinateAxis} Handling of CNAMEia standard FITS keys that
	contain the preferred coordinate labels.

	[TWEAK] {FITS} Some header keys in output images are deprecated (but
	still written for now for backward compatibility), in favor of new
	keywords based on the standard beam definitions based on BMAJ, BMIN, 
	and BPA. Thus:

		SMOOTH (arcsec) --> SBMAJ, SBMIN, SBPA (radians)
		EXTFILTR (arcsec) --> XBMAJ, XBMIN, XBPA (radians)
		CORRECTN (arcsec) --> CBMAJ, CBMIN, CBPA (radians)
	
	Also introducing IBMAJ, IBMIN, and IBPA to record the underlying 
	instrument beam properties.	

	[TWEAK] {Data2D} improved header parsing (BUNIT, EXTNAME).

	[TWEAK] {GridImage} fftFilter updated to use the much faster new FFT
	classes instead of the old.

	[TWEAK] {GridImage} Removed hardcoded (angular) units to better support
	general purpose images. Header editing/parsing to use smarter units.
	(arcsecs for sperical grids, and standard units otherwise. Preferred
	grid units can be set and queries via get/setPreferredGridUnit().

	[TWEAK] {SphericalCoordinates} Changed default decimal formating to 
	0.01 s resolution (from 0.001s).

	[CODE] {SignificantFigures} There appears to have been a regression
	in DecimalFormat, on which SignificantFigures was based, by which
	the overridable format methods were not called. Thus, 
	SignificantFigures is now derived directly from NumberFormat to work
	around it. Various classes had toString(DecimalFormat) methods, which
	have now been changed to toString(NumberFormat).



0.05-3 (13 January 2014)


	[NEW] FloatFFT and DoubleFFT now both have a NyquistUnrolledRealFT 
	subclasses which store the Nyquist frequency component as an extra 
	packed complex value at the end. Thus, these transforms take float[] or 
	double[] data with sizes 2^p + 2, respectively. The base classes 
	FloatFFT and DoubleFFT remain packed in the convention of Numerical
	Recipes, with the Nyquist component stored in the imaginary component
	of the index 0 (constant) complex value.

	[FIX] {GridImage} Fixed weight normalization when re-smoothing. Also
	improved the CLEAN-type deconvolution algorithm.

	[FIX] {MultiFFT} Proper handling of Nyquist frequencies (in last index)
	on real transforms. The Nyquist component is now included as an extra
	complex value (2 extra real values) at the end of the bottom float[]
	or double[] arrays. Thus, multi-dimensional arrays used for real 
	transform have dimensions [n1]...[nm], where all by the last dimension 
	is a power of 2, whereas the last dimension nm is 2^p+2 to properly 
	accomodate the Nyquist components in that direction.

	[TWEAK] {Configurator} Added static 'silent' switch. If enabled the
	Configurator won't report on loading config files.

	[SPEED] {FFT} Faster bit reverse boosts FFT speeds by ~5%.


0.05-2 (9 December 2014)
	
	[FIX] Reporting the configurations loading on console is reinstated.


0.05-1 (21 August 2014)

	[TWEAK] {ColorBar} connected to ImageLayer not ImageArea.

	[TWEAK] {SignificantFigures} Format numbers with no decimal part as
	integers (e.g. simply '42' instead of '42.0').
	
	[TWEAK] {FancyRuler} colliding labels skipped for cleaner look.
	(works even on reversed axes, and unsorted custom divisions).
	
	[TWEAK] {plot} Generalized ImageLayer.

	[TWEAK] {plot} enabling/disabling rulers made easier.

	[FIX] {plot} Initial sizing, resizing, and validation.

	[FIX] {plot} default axis labels.


0.04-4 (6 August 2014)

	[BUG] {EquatorialCoordinates} RA direction inadvertently inverted when
	printing equatorial coordinates. Introduced in prior release. Now 
	fixed.



0.04-3 (9 July 2014)

	[BUG] {AngleFormat} Was still broken, now for all negative angles.

	[TWEAK] {sphericalCoordinates} static method get/setDefaultDecimals() 
	added to control how toString() will format angles by default. Also
	toString(int decimals) method added to provide control on an ad-hoc 
	basis also.

	[TWEAK] {Precession} Made concurrent safe (no more recycled temporary
	storage, but still just as fast, or even faster than before.)

	[TWEAK] {Util} All decimal formats extended up to 12 decimals, 
	including Angle (afN), Time (tfN), and HourAngleFormats (hfN). Like 
	decimal formats, these are also available in simple array lookup form
	(E.g. Util.af[3] = Util.af3); 



0.04-2 (19 June 2014)

	[BUG] {AngleFormat} Angles between 0 and -1 degrees were wrongly parsed
	as positive angles. Fixed.

	[BUG] {EclipticCoordinates} Greek letters (axis labels) in FITS headers
	make FITS unreadable.

	[TWEAK] {Precession} Changed to be threadsafe. 

	[JAVA] Recompiled for Java 1.6.



0.04-1 (2 June 2014)

	[BUG] {Data2D} Gaussian smoothing beam had missing values on axes.

	[BUG] {dirfile} Little-endian byte-reorder was botched. Fixed.

	[BUG] {SphericalProjection} Projection orientation issue due to 
	incorrect native pole in most projections. Zenithal (ZEA, SIN, TAN) and
	GLS projections were unaffected by this bug.

	[BUG] {Grid2D} Inverse transforms were wrong when not a square grid.
	Fixed.

	[NEW] {CelestialCoordinates} getEquatorialPositionAngle() returns the
	orientation of the longitude axis relative to equatorial longitude. 

	[NEW] {Data2D} Smoothing with rotated Gaussian.

	[NEW] {text} FixedLengthFormats imported from xcrush.

	[NEW] {Data2D} {GridMap} A few new useful methods.

	[NEW] VAXDataInputStream for handling native VAX data format
	(e.g. for SHARC).

	[NEW] imported LittleEndianDataInputStream from APEXBridge2.

	[NEW] PolygonalRegion moved from crush.

	[NEW] Imported Matrix support from xcrush.

	[NEW] Imported ArrayUtil, and dependent classes/interfaces from xcrush.
	(removed ArrayData, which is no longer needed).

	[NEW] Rulers are starting to look good :-).

	[NEW] Added log and sqrt scaling to ImageLayer.

	[NEW] Added Stereographic (STG) and Zenithal Equidistant (ARC) 
	Bonne's Projection (BON), Cylindrical Perspective (CYP), Cylindrical
	Equal Area (CEA), Parabolic (PAR), and Polyconic (PCO) projections.

	[NEW] Added optional FITS WCS keywords WCSAXES and WCSNAMEn to map
        coordinate descriptions.

	[NEW] {util.ExtraMath} roundupRatio(a, b) introduced, which returns
	the rounded-up ratio of two integers (or longs).

	[RENAME] CelestialProjector -> AstroProjector.

	[BUG] {MultiFFT} Radix-4 was still broken due to badly compactified
	indexes. Now fixed.

	[FIX] {AngleFormat} Extra 0 digits when seconds round up to 10 has
	been fixed.
	
	[FIX] {FFT} Eliminated some unneeded InterruptedExceptions.

	[TWEAK] {AstroTime} Fits date formatting made consistent.	

	[TWEAK] {EquatorialCoordinates} Conversion to horizontal simplified.

	[TWEAK] {Data2D+} addDirect() extended to superclasses of GridMap and
	properties, such as smoothing, are taken into account also...

	[TWEAK] {AstroTime} Conversion to and from strings assumes UT times
	(no leap seconds needed). Separate new methods can be used for UTC
	comversions.

	[TWEAK] {LeapSeconds} can suppress error messages from LeapSeconds via
	setVerbose().

	[TWEAK] {GaussianSource} Adaptive integral tweaked with a smaller 
	incremental change criterion.

	[TWEAK] {Grid2D} SphericalGrids labelled with XXLN and XXLT are now
	understood as by Calabretta & Greisen (2002).

	[TWEAK] {Grid2D} Choose correct Grid2D class for FITS header.

	[TWEAK] Configurator.toString() now returns the option argument. This
	allows for more elegant code that omits explicit .getValue() calls.

	[CODE] {SphericalProjections} Support for inverted axes (lat/long vs
	long/lat).

	[CODE] Cleanup of the spherical projections code. Removed duplicate
	sin()/cos() calls, general performance tweaks, and better FITS support.
	Made sure spherical coordinates are set natively.

	[CODE] {kovacs.plot} Work on plots. Some fixes to rulers and side 
	panels. Still under construction...


0.03-1 (9 December 2013)
	

	[NEW] Added some math interfaces, while thinking of a generic
	parser for expressions.

	[NEW] Configurator now has getSign(), which returns -1, 0, or +1
	depending whether the argument is negative, zero, or positive. It
	also understands '-', '*', and '+' to mean the same thing, as well as
	'positive', 'negative', 'plus', 'minus', 'pos', 'neg', or 'any' .

	[NEW] LocalAverages now have the ability to get consistency check 
	values before averaging based on a reference value. Based on this
	it is possible to get a checked avearage value, where a second-round
	aevraging is consistency checked against the mean of the first round.

	[FIX] {MultiFFT} (What used to be called GenericFFT). Many many fixes. 
	As a result it now seems to work More testing is needed to be sure...

	[FIX] {Coordinate2D} Parsing of coordinates from text has been revised.
	It also provides more useful error messages, when the parsing fails.

	[FIX] {dirfile} Little-endian reading of longs fixed, and streamlined
	all little-endian conversions. 

	[FIX] GridImage.regridTo(image) did not use the correct intermediate
	image size. Now fixed.
	
	[SPEED] {MultiFFT} Much improved parallelization of Multi-dimensional
	(and general FFTs).

	[CHANGE] Coordinate2D.getX() and getY() renamed to x() and y() for
	simplicity.
	
	[CHANGE] FFT APIs changed slightly for better consistency and 
	separating 1D FFTs from multi-dimensional ones (e.g. padding and
	average power).




0.02-2 (19 August 2013)

	[NEW] cbrt() added to Complex.
 
	[CODE] Added Serialization to some classes (just a beginning...)

	[CODE] HashCode to deal with Object[] arrays more comprehensively.

	[CODE] Added hashCode() to Data2D().


0.02-1 (15 July 2013)

	[BUG] Complex division bug found and fixed.

	[BUG] Comparison of Units was messed up with the multiplier comparison.

	[NEW] WeightedPoint multiplication and division operations.

	[NEW] Division interface. Applied to Complex and CompoundUnit.

	[NEW] Hankel functions.

	[NEW] Zeta function evaluations for Complex arguments 

	[NEW] Complex gamma function with Lanczos approximation. Also complex
	BetaFunction.

	[NEW] Brought in a bunch of interfaces from xcrush.util.math, and
	applied these to classes where appropriate. This is one small step
	towards reintagrating the extensive xcrush brach of utilities.

	[NEW] Added Javadoc stems. These are generated by JAutodoc so some of
	the automatically generated javadoc is nonsensical. In time, it should
	be filled with meaningful documentation.

	[NEW] Statistics.lineFit expanded for different argument type 
	scenarios.

	[NEW] Imported math.specialfunctions from xcrush.

	[NEW] ExtraMath class with math functions migrated from Util.
	
	[NEW] fits.FitsExtras class with FITS functions migrated from Util.

	[NEW] Added data.FauxComplexArray (Float and Double) for performance 
	applications. FauxComplexArrays outperform proper Complex[] arrays
	because of the reduced memory (hence caching) requirement. Below is
	a summary of the storage required, per element, in each type:
	
		Complex[]: 			32 bytes
		FauxComplexArray.Double: 	16 bytes 
		FauxComplexArray.Float: 	8 bytes

	The performance advantage becomes significant (2-3x) for arrays 
	comparable to, or larger than, the CPU cache size.

	[NEW] Added fft.ComplexFFT (tested). For large data, Complex FFTs are
	a 2-3 times slower than the same sized float or double FFTs. Therefore
	if performance is a concern, one should use FauxComplexArrays with
	their appropriate FFTs instead of proper Complex FFTs...

	[FIX] Comparison of angles in SphericalCoordinates could misbehave
	when the two angles were + and - of 0 within the requested precision.
	Now fixed.
	
	[MIGRATE] Various classes migrated from kovacs.util to kovacs.math
	and kovacs.projection. Also from kovacs.astro to kovacs.projection.

	[MIGRATE] Util.lineFit -> data.Statistics.lineFit.

	[MOVE] CurrentTime -> util.astro.
	
	[RENAME] Simplified package names, e.g. kovacs.util.fft -> kovacs.fft.
	
	[RENAME] Data -> ArrayData.

	[RENAME] Datum -> DataTable.Entry. 
	
	[RENAME] CoordinatePair -> Coordinate2D.

	[TWEAK] Some optimization tweaks to GridMap/GridImage index<==>offset
	conversions.

	[TWEAK] WeightedPoint add/subtract optimized to require fewer and 
	faster operations.
	
	[TWEAK] CompoundUnit simplified to contain only factors. Also made
	to work better, in general.

	[TWEAK] erf() to hanfle infinite arguments, and Cumulative normal 
	distribution to return infinite values.

	[TWEAK] Old, slow, and not too precise ConfidenceCalculator replaced
	with math.specialfunctions.CumulativeNormalDistribution.

	[TWEAK] {FFT} Further small performance tweaks to FFT classes, 
	reaffirming that these are faster than FFTW's famously fast FFTs. This 
	is especially true for parallel processed FFTs!

	[TWEAK] Cosmological constants updated in Constant.java.

	[TWEAK] Util constants (twoPi, rightAngle, sigmasInFWHM, log2 etc.) 
	moved to Constant. Spread use of twoPi and rightAngle where 
	appropriate.

	[TWEAK] Some tweaking/cleanup of Util. Faster getBoolean(String)
	and standardAngle().

	[TWEAK] Some tweaks to Vector2D and Complex classes, adding new 
	functionality and speeding up others.
