public GTreeNode getViewRoot() {
		return realViewRootNode;
	}
This method returns the root node currently being displayed by the {@link JTree}. If there
are no filters applied, then this will be the same as the model root (See
{@link #getModelRoot()}). If a filter is applied, then this will be a clone of the model root
that contains clones of all nodes matching the filter.

@return the root node currently being display by the {@link JTree}
