future python module required

[DrHashi]

After installation via pip, it required builtins module to be available which is part of future.

I believe this should be included as part of the documentation

Traceback (most recent call last):
  File "/usr/local/bin/amicleaner", line 7, in <module>
    from amicleaner.cli import main
  File "/usr/local/lib/python2.7/dist-packages/amicleaner/cli.py", line 6, in <module>
    from builtins import input
ImportError: No module named builtins

Solution:

pip install future
