//##################### BUS ROUTE DIALOG #####################

//Bus Route Dialog:	Consists of the Bus Route List and a Delete Bus Route button 
//					Dialog appears only when the Bus Route Object is selected
//Bus Route List:	Displays all Bus Routes stored at the moment the dialog is 
//					accessed. When a Bus Route is selected the Map Canvas will
//					indicate the Bus Route accordingly
//Delete Bus Route:	Deletes current Bus Route selected.
