Work Progress - Jan 11 - Jan 15

Finished rendering the statement tree in Scriptlet window

• I've set up an example in the skateboarder code (SB/BoarderEngine.java). I create an event for the BoardEngine called DummyEvent. It is accessible under the Events tab on the left window as soon as we run SB/SBGui.java, at which time the stuff associated with the Engine are loaded. Click on it, and you'll see the methods associated to it displayed.
  
• Rendering of the statement is delegated to the individual statement types. In this example statement tree, in the Something2() method we have parameter val being evaluated by a binary statement "x + x". the rendering of the binary statement part is depending on the existing implementation in the class JPnlLineBinary.
• Fix the problem that when another object is selected, the statement tree in the scriplet window is not clear.
• Fix the problem that the method's parameters are not immediately shown after the corresponding object is selected.
