Feb 08, 2014 - Removed support for Python 2.6. Added write support for JP2
Feb 09, 2014 - Removed support for Python 2.6. Added write support for JP2
UUID, DataEntryURL, Palette and Component Mapping boxes, JPX
Association, NumberList and DataReference boxes. Added read
support for JPX free, number list, data reference, fragment
table, and fragment list boxes. Palette box now a 2D numpy
array instead of a list of 1D arrays. JP2 super box constructors
now take optional box list argument. Fixed bug where JPX files
table, and fragment list boxes. Added get_printoptions,
set_printoptions functions. Palette box now a 2D numpy array
instead of a list of 1D arrays. JP2 super box constructors now
take optional box list argument. Fixed bug where JPX files
with more than one codestream but advertising jp2 compatibility
were not being read.
