Pyreshaper

-------------

- Bugfixes

-------------

- New I/O backend manager. Can work with netCDF4 or PyNIO.
- Removing hierarchy to Reshaper classes, as there is only 1 (similarly
removing hierarchy of matching Specifier classes)
- No longer requires PyNIO to install...but you need netCDF4 or PyNIO to
run the reshaper!
- Adding ability to treat all 1D time-dependent variables as metadata
with only one command-line option
- Adding ability to extract out only some time-series files, instead of
requiring all time-series files be extracted. This option should be
used sparingly and with caution!
- Adding the ability to "chunk" over user-specified dimensions when
reading and writing. This finally allows for some control over memory
use!

--------------

- Python 2.6 back-porting

-------------

- Split 'slice2series' script into 2 separate scripts: 's2smake' to generate
specifier object files (specfiles), and 's2srun' to run a reshaper job
with a given specifier object file
- Now uses 'write mode' to determing if overwriting output files or skipping
existing output files
- Added capability to append to existing output files

-------------

- Fix bug in the 'slice2series' script
- Adds a write to file option for the Specifiers
- Modifying output message verbosity settings

-------------

- Newly automated versioning information
- Bugfixes, performance improvements
- New yellowstone testing code
- Now measures read/write times separately in diagnostic data
- Performance improvement (no explicit loop over time-steps in a time-slice
file needed)
- Enabling user-defined compression level for NetCDF4 output
