 Finally, most education on the subject emphasize sets and membership functions, but fail to mention the importance of the domain (or "universe of discourse"). It's easy to miss this point if you get lost with set operations and membership values, which are actually not that difficult once you can *play* and *explore* how these things look and work!
 
 ### The Idea
-So, the idea is to have three parts that work together: domains, sets and rules. Each of these classes wrap additional logic around basic building blocks - Set gives logical operations to simple functions, Domain gives additional logic to numpy arrays and group Sets together while Rule combines different Domains. You start modelling your system by defining your domain of interest. Then you think about where your interesting points are in that domain and look for a function that might do what you want. In general, fuzzy.functions map any value to [0,1], that's all. Simply wrap the function in a Set and assign it to the domain in question. Once assigned, you can plot that set and see if it actually looks how you imagined. Now that you have one or more sets, you also can start to combine them with set operations &, |, ~, etc. It's fairly straight forward.

 Finally, use the Rules to map input domain to output domain to actually control stuff.
 ### Warning: Magic
 To make it possible to write fuzzy logic in the most pythonic and simplest way imaginable, it was necessary to employ some magic tricks that normally are discouraged, but at least there's no black magic involved (aka meta-programming etc.), so things are easy to debug if there is a problem. Most notably:
