Can this functionality be committed to the opentok-whiteboard, I have already added this functionality to my cloned repo.

Sure, can you submit a pull request?

1) Added Undo Redo Functionality, also supports mobile devices. 2) Added javascript confirmation box on clearing whiteboard as undo/redo is impossible after clearing Whiteboard.
