python - ip: Bump version to 0.3 and add python.py module.

Log Message:
-----------
Bump version to 0.3 and add python.py module.

python.py provides basic functionality for creating a *_python command. It
provides interface laying and module invokation with the attempts to be mostly
inline with the basic functionality of the standard python command.

Additionally, add a subclass check to test/abstract.py and create test/'s
__init__ file.
