Cleaned up code to match prar branch better
MAJOR improvement on distrubuted IPN collision avoidance

The two main changes are:
No upper limit on t_go.
Remove checking if threatPlane is behind thisPlane.
Evaluation node added.. *buggy*

I am in the process of adding evaluations to the algorithm.
The course generator + auto-evaluator is from Phil.
Fixed bugs related to new evaluator node and removed test course files
