Questions regarding the ElasticAI.Creator

Message from @Sillobear. Moved from PR #306.

So here are my first few questions:

• How does Binarize work?
• As an end user which Arithmetics Class do I need? Is it actually meant for end users?
• Is it that we, so far, only use Fixed Point Arithmetics? If yes, what is the Reason?
• Why is round_to_fixed_point/float in the autograd_functions directory?
• Is the autograd_functions Directory actually for Autograd Functions?
• Is base_module meant to generalize the Layers in perspective to Arithmetics?
• As a contributor, how much must I know about the vhdl subdirectory?

Also as an idea:
maybe we could list possible entry points for new contributors/"HiWis" and users.
Something like mini projects, simple issues, and maybe non-code commits?
Just an idea.
