Add wrapt library

The wrapt library makes decorators much more useful than
with just regular decorators, especially in cases where
the decorator wants to know what object it is attached to.

Docs @ http://wrapt.readthedocs.org/
Module @ https://pypi.python.org/pypi/wrapt

Projects that would like to use this to create a more
universal decorator method:
 - TaskFlow
 - Rally
 - Others?
