Refactor of the event system

[goodman17c]

Events are based on a binary representation for event types.
This refactor allows for more complexity of event types and simplification of code and development.

Alterations should have more comments to alleviate readability issues. Failed unit test suit. Output below:

Love the idea! But, does it pass the tests? Also, did you make sure that it runs in Numba mode as well @goodman17c ?

[ilhamv]

It passes the tests and runs on Numba mode
