Added Python module to work around strings/list issue.

Essentially, it's not possible to call getattr(...) in the Python 3 builtins,
since the strings are interpreted as lists, getattr barfs. This code wraps the
builtin for getattr as well as making calls to a callable attr. It does so by
accepting binaries from Erlang, which get converted to Python bytes and can
easily be converted to strings once in Python.
Updated ignores.
This whole module is python; removed py-prefixes.
Updated to call the new lsci.obj Python functions.
Wrap the first NumPy functions.
Added NumPy version info.
Added link to numpy docs and added numpy version.
