'''
This file is used for filter. Each filter contains different Options. And should be used for different format types.
If you don't find a fitting filter then program it in this file to structure your coding.
If there is a similar Filter which does not perfectly fit into your code, please extend this Filter instead of creating a new one

Another Note: Try to keep up with this format: so with a lot of "coding Notes", the Class system and the variable_names
If you have to use non-class filter please describe why and when to use this non-class filter

    This filter, takes a Key(axe) which maps on Values on a Matrix
