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 disables builtin functions (and one exception class) which are
+removed from Python 3.3.
+
+This module is designed to be used like this::
+
+    from future.builtins.disabled import *
+
+This disables the following obsolete Py2 builtin functions::
+
+    apply, cmp, coerce, execfile, file, input, long,
+    raw_input, reduce, reload, unicode, xrange
+
+We don't hack __builtin__, which is very fragile because it contaminates
+imported modules too. Instead, we just create new functions with
+the same names as the obsolete builtins from Python 2 which raise
+NameError exceptions when called.
+
+Note that both ``input()`` and ``raw_input()`` are among the disabled
+functions (in this module). Although ``input()`` exists as a builtin in
+Python 3, the Python 2 ``input()`` builtin is unsafe to use because it
+can lead to shell injection. Therefore we shadow it by default upon ``from
+future.builtins.disabled import *``, in case someone forgets to import our
+replacement ``input()`` somehow and expects Python 3 semantics.
+
+See the ``future.builtins.misc`` module for a working version of
+``input`` with Python 3 semantics.
+
+(Note that callable() is not among the functions disabled; this was
+reintroduced into Python 3.2.)
+
+This exception class is also disabled:
+
+    StandardError
