Created Tree Branch
Includes Tree Model and Node Classes
Copied Controller and RequestObserver from ListView to retrieve Requirements from the database
Added Iteration class.
Fixed nullPointerException
The files in Iteration package need to be modified. They do not build for now. The ToolbarPanel works fine.
Tree will now load in requirements when it is focused (on start up)
Refresh Button loads in requirements (will make it auto-refresh later)

Bug: Refresh button will re-add requirements that are already in the list
Put in some more files for the Iteration model. Cleaned up some code. Put in basis Iteration tests.

Merge branch 'team1-iteration-class' of github.com:/cmdunkers/wpi-suite-tng into team1-iteration-class

Conflicts:
	RequirementsManager/src/edu/wpi/cs/wpisuitetng/modules/RequirementsManager/Iteration/IterationPanel.java

	RequirementsManager/src/edu/wpi/cs/wpisuitetng/modules/RequirementsManager/Iteration/SaveIterationController.java
registered the iteration manager with the core in file wpi-suite-tng/Core/WPISuite/src/edu/wpi/cs/wpisuitetng/ManagerLayer.java the registry should read "iterationmanageriteration" I think. Added the entire iterationstore class, you know the drill, database stuff, stores stuff in the Iteration class. Speaking of the Iteration class, I added the methods that it needed to actually work with the DB. I hope this actually is good code.
so, I fixed all of the build errors in my code, one thing that I had to do was put a dummy addIterations function into IterationView some GUI people will need to take a look at it and make it actually do something with the Iterations that it gets.
click on new iteration brings up a new tab. need more work on IterationPanel.
Merge remote-tracking branch 'origin/team1-iteration-class' into team1-iteration-class
Added DatePicker for Iteration. Could not build because of being on a lab computer (SDK install not permitted).

Have DatePicker working.
Minor fixes.
