/**
The GuiController class is responsible for constructing the GUI Framework for the 2dfQSO system
Its split in a number of panes. 

There are two splitpanes 
1) splitPane - This is the pane which splits the window in two panes
	a) query pane on the left (leftPane)
	b) outputpane on the right (RightPane)
	
2) The rigthPane adds the following splitPane
   splitOutput - This splitpanes splits the pane in two sections
	a) Pane to describe the output results in table form
	b) pane to perfrom operations on the data results like Save, Vo-Plot etc
	
Bugs : Need to be able to resize the object
