package.ps1 now fetches all dependencies
Don't literally check in Python since it looks dodgy (rightfully so). Instead the build script just fetches it. * Update README, simplifying language and documenting other projects

-compat
-======
-
-Cross-compatible functions for Python 2 and 3.
-
-Key items to import for 2/3 compatible code:
-* iterators: range(), map(), zip(), filter(), reduce()
-* lists: lrange(), lmap(), lzip(), lfilter()
-* unicode: u() [u"" is a syntax error in Python 3.0-3.2]
-* longs: long (int in Python 3)
-* callable
-* iterable method compatibility: iteritems, iterkeys, itervalues
- * Uses the original method if available, otherwise uses items, keys, values.
-* types:
- * text_type: unicode in Python 2, str in Python 3
- * binary_type: str in Python 2, bytes in Python 3
- * string_types: basestring in Python 2, str in Python 3
-* bind_method: binds functions to classes
-
-Python 2.6 compatibility:
-* OrderedDict
-* Counter
-
-Other items:
-* OrderedDefaultDict
