Genomedata

* DO NOT USE: genomedata-load-seq doesn't work
* allow use with PyTables >=2.2
* new command: genomedata-info: "genomedata-info tracknames ARCHIVE"
prints the tracknames for ARCHIVE
* Genome.format_version will now return 0 when files are missing a
genomedata_format_version attribute
* Genome.__init__: future-proof to future versions of file format by throwing an error
* tests: add regression tests, lots of changes
* docs: add man pages

* genomedata-load: will now support track filenames with "=" in the names
* genomedata-load: now supports UNIX glob wildcards as arguments to -s
* genomedata-load-data: allow other delimiters besides space for
variableStep and fixedStep, allow wiggle_0 track specification
* genomedata-load-data, genomedata-load: remove unused --chunk-size option
* genomedata-close-data: fix bug where chunk_starts, chunk_ends not
written for supercontigs with zero present data
* installation: move from path.py to forked-path
* docs: fixed small errors
* various: removed exclamation marks from error messages. It's not *that* exciting.
* some portability improvements
* tests: improve unit test interface

* Fixed an installation bug where HDF5 installations later in
LIBRARY_PATH might override those specified first, leading to
linking errors during build.

* Added support for adding additional tracks using genomedata-open-data and
Genome.add_track_continuous().
* Added support for creating Genomedata archives without any tracks.
* Made chromosome.start and chromosome.end be based upon sequence instead
of supercontigs.
* Made iter(chromosome) and chromosome.itercontinuous() yield supercontigs
sorted by start index (instead of dictionary order).
* Fixed pointer dereference bug that could cause segfault in
genomedata-load-data.
* Improved installation script robustness and clarity.

* Fixed format string warnings on Mac OS X
* Included Gnulib for Mac OS X support
* Updated docs to reflect OS X support

* Fixed format warning on 32-bit systems
* Fixed Ubuntu format string warnings (switched fprintf to fputs)
* Fixed bug that caused segmentation fault when accessing
tracknames_continuous before data when Genome was not used as a
context manager.
* Created a uniform interface for loading Genomedata archives, whether they
are a directory or a single file (untested). This includes calling improving
the handling of non-context-manager Genome objects by requiring a call
to Genome.close() when finished.
* Added an option to genomedata-load-seq and genomedata-load
to specify the Genomedata archive implementation (directory/file).
Default is directory if number of sequences is at least 100.
* Added support for replacing data in Genomedata tracks.
* General documentation improvements
