Inital Basis for Airplane Ai- not complete

This is the code I finally worked up time to sit down and crunch out, briefly, for an airplane Ai. I am still reading through the code for comprehension so the Ai can be implemented (the logic to be completed afterwards) to calculate the player's skill at runtime and adjust to stay competitive.

The reason the most accurate "ai type" is of type SUICIDE is because of the plane's nature to chase the player although never reaching them due to a slower acceleration/ thrust. I realize that in the game we are replicating, ALL of the planes essentially are suicidal, however these other Ai modes are present as a challenge for the player as they aim to kill and not be killed, and for us as programmers to write a challenging Ai.
