Influence.py __init___ & run_influence merge?

[JGASmits]

The influence command functions are scattered between the init part of the influence.py and the .run_influence command. Perhaps this is needed for some multi-threading that i'm not aware of, in that case feel free to close this issue.

But I think it would greatly increase understandability of the code if everything is bellow the init instead of spread to two different functions (with the function defenitions also being spread out over regular functions and functions part of the class object).
