Commit of first tests, I did not take out debug println's. Much smart!
Very Fun!
Add SchedulerServiceImpl tests
Added JobPriorityComparatorTest
Fixed a small bug so that testing becomes possible. 

getWorkerThread should return an Array of WorkerThreads but the cast for
from Object[] to WorkerThread[] doesn't work (anymore). Specifying that
toArray function from List should expected an array of WorkerThreads
fixes this.
- Added tests for WorkerThreadImpl
- Extended tests for SchedulerServiceImpl
- Removed sysouts in inappropriate blesses (move along now nothing to
see here)
Finished tests
Added code for testing
refactored all tests to be compatible
