Updates for array index out of bounds exception
I guess Travis doesn't like java 7
Whoops, I had changed raceNumber to 0 and never changed it back
Added regression tests for GRP
removed unused import statements in Race and RaceAbstract and updated comments. Changed event() in eventHandler: if the event type is changed and race is not null, race, currentlyRunning, racerQueue, racerLanes, and trigMementos are set to null so that a new race matching the new event type will be created when the user enters a racer to the new race.
