Controller Attributes

[SimonRubenDrauz]

The basic controller class contains three atrributes I would recommend to remove from there: initial_run, index and recycle. Instead I would move them to the net.controller-DataFrame. recycle and index are already there, initial_run I would also add.

Following reason: Right now index and recycle have been declared twice: once in the controller class and once in the net.controller-DataFrame. That means, if I change one of them in the aftermath of the initialization, they would be suddenly incosistent. I guess the controller-attribute is the leading parameter, therefore everything in the DataFrame is ignored (even if the user changes it).

What do you think? If you agree, I would change it and create a PR.
