I try to comment everything important but I already got the response that it is not good enough...

So if guys have any advice on how I could comment it better I try to do so.
I don't know who already took a look at the code but it seems to be hard to understand for some, so if you have any request about something to document and/ or how just tell me.

In the end I don't want that it is no use to anyone because it's too hard to understand.
