Geometry tutorials translated into Python.

[PPaye]

This Pull request:

Adds a Complete translation of the Geometry-Tutorials into python.

Changes or fixes:

It runs, it re-reruns, and it gets out of IPython without crashing memory. The Root-Objects have been cautiously removed once they have been created by pyroot, this helps to run the scripts again-and-again without crashing memory, since ROOT hasn't the ownership of the Objects anymore. Enjoy the pygeom tutorials, if so.

Checklist:

• [ yes] tested changes locally
• [ yes] updated the docs (if necessary)
• [ yes] synchronized forked with master(latest-stable)
