There is no function to efficiently erase the dots without re-initializing the board

I would like to remove the dots and draw others without redrawing the board.

I figured it out. You have to draw() the Fretboard, then add a Paper.JS layer, and then let it draw the nuts. You can then clear the board from the nuts by doing paper.activelayer.children.remove and an paper.view.update.
