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.

+Metaclasses
+-----------
+
+Python 3 and Python 2 syntax for metaclasses are incompatible.
+``future`` provides a function (from ``jinja2/_compat.py``) called
+:func:`with_metaclass` that can assist with specifying metaclasses
+portably across Py3 and Py2. Use it like this::
+
+    from future.utils import with_metaclass
+
+    class BaseForm(object):
+        pass
+
+    class FormType(type):
+        pass
+
+    class Form(with_metaclass(FormType, BaseForm)):
+        pass
