future 0.0.3

[experimental] support Python 2 with fewer warts

The ``future`` module helps run Python 3.x-compatible code under Python 2.

It allows people to write clean, modern Python 3.x-compatible code today
and to run it with minimal effort under Python 2 alongside a Python 2
stack that may contain dependencies that have not yet been ported to
Python 3.

It is designed to be used as follows:

from __future__ import division, absolute_import, print_function
from future import (common_iterators, disable_obsolete_builtins,
str_as_unicode)
from future.features import super, range

followed by clean Python 3 code (with a few restrictions) that can run
unchanged on Python 2.7 or Python 3.3.

Soon we may also support this:

from future import standard_library

to bring in the new module names from the Python 3 standard library, so
imports like this will work on either Python 2.7 or Python 3.3:

import builtins
import configparser
import queue
# etc.: see standard_library_renames module for more info.
