Thank you!

Wow, this might be exactly what I want! Thanks to the pythonness
(syntax) the code might even be shorter then implementing it in C#!

Gonna go and play around with this some more(now), and can't wait til
I get home (there will be some massive code cleaning).

I wonder why I've never come across this before, feels like i've
googled alot these last weeks.

Python has grown in my eyes.
