The way I'm trying to implement this feature is by cataloguing the indexes of the start and end of the routes and then using map.getOverlays().remove(index) in a loop to go through and remove all of the overlays created by DrawPoints. I'm going to be working on that today so I'll let you know how that goes. It's good that someone else is trying to do this too!
