WCON for Python Beta Release 1.0.0

Also available at the Python Package Index https://pypi.python.org/pypi/wcon/1.0.0, so install via:

pip install wcon

Release notes (Python):

• Performance improvements (#55) (see summary of performance below)
• Changed internal representation of worms from a single DataFrame to an ordered dictionary of DataFrames, with the keys being the worm IDs. API has not changed; .data is now a lazily evaluated property, while .data_as_odict is a property that gives direct access to the internal representation. (#73)
• Can read and write Zip files (#59)
• Units support scalar multipliers (e.g. "0.04*s" are the units for frames 1,2,3 going at 25 FPS) (#66)
• The schema for metadata allows more of what's actually allowed in the specification. (#53)
• As with prior releases, this works for both Python 2.7 and 3.3+.
