Check in `future` package

I hit some issues installing Whisper and had to embed this package.
I haven't taken the time to deeply understand what's going on. I think
that embedded Python follows different rules about resolving module
paths than regular system Python.

Basically, `future`'s setup.py has a line like `import src`, where
`src` is a module inside future (like `future/src/__init__.py`). This
doesn't work unless we put that directory on the search path.

+'''
+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..."
