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

-'''
-This module provides a newsuper() function in Python 2 that mimics the
-behaviour of super() in Python 3. It is designed to be used as follows:
-
- from __future__ import division, absolute_import, print_function
- from future.builtins import super
-
-And then, for example:
-
- class VerboseList(list):
- def append(self, item):
- print('Adding an item')
- super().append(item) # new simpler super() function
-
-Importing this module on Python 3 has no effect.
-
-This is based on (i.e. almost identical to) Ryan Kelly's magicsuper
-module here:
-
- https://github.com/rfk/magicsuper.git
-
-Excerpts from Ryan's docstring:
-
- "Of course, you can still explicitly pass in the arguments if you want
- to do something strange. Sometimes you really do want that, e.g. to
- skip over some classes in the method resolution order.
-
- "How does it work? By inspecting the calling frame to determine the
- function object being executed and the object on which it's being
- called, and then walking the object's __mro__ chain to find out where
- that function was defined. Yuck, but it seems to work..."
