Clean up globals() for python interactive sessions

Browse source 
Previously the global namespace of all interactive python session were
polluted with all the stuff we did in this initialization script. For
example, globals()['__doc__'] would show the docstring from this file.

While none of this was ciritical, it could be confusing sometimes. So
this commit fixes that.
