Analytical_Engine: Remove all private graph collections from the Analytical_Engine

#### Broken rules:

Many graph methods in the Analytical_Engine make use of various static collection to store values. These are better handled as arguments being passed to those private methods as those global variables are inherently a bit dangerous, and also makes it so that you can only work with one graph at the time.

#### Suggestions to restore compliance:

Refactor out the need for all private static faileds in the ANalytical_Engine
