Set up testing
Moved guessing_game file into lib where it belongs.
Added a binary file, so that it controls the gameboard

This allows us to have a custom introduction, determine the order
of events that are not strictly game related.
Any kind of external structure, competition announcements, ads,
whatever.
We added some Class Level things before game is instantiated

We can give an introduction
We can ask for a name (Not stored in game at that time)
We can ask for maximum number, and for choice.

At this time, we use those returns to use for the Game initialization.
