 /** Due to the TreeModel objects not having any synchronization, certain assumptions, such as the model state remaining constant during a repaint, don't always hold - especially given that I'm changing the tree model on a different thread. In order to get around this I will use the latest swing paradigm wherein you flag a section of code to be executed by the AWT GUI Event queue, as soon as other gui tasks have finished. This way I shouldn't have tree redraws throwing NPEs because the array size of the children of a certain node has changed -while- the repaint call was made, i.e. repaint() calls getChildCount() = 13, removeNodeFromParent() called, repaint calls getChildAt(12) = ArrayIndexOutOfBoundsException.
