A2 : notes on implementation of GameEngine2

[eyeshield2110]

• Alternate GameEngine implementation: declaration in GameEngine2.h and definition and testing in GameEngine2.cpp
• Implemented the FSM diagram from A1 as a literal graph, using State objects as the nodes and Transition objects (valid commands) as the edges.
