Fixed tree view updating
Added test to IterationValidator which confirms functionality of overlapExists method
Fixed a bug (tab should have been focusabletab, not jpanel)
Updated overlap test case to test validation rather than method for overlap detection.
Added baseline tests for requirement update in entity manager.
Replaced iteration text box with iteration combo box that shows the available iterations. Does not currently save the iteration to the requirement or retrieve the requirements iteration. The code for saving the iteration text box value and the listeners have been replaced with TODOs to be filled with the code for working with the combo box.
