Tableaunoir for making presentations

[francoisschwarzentruber]

I would like to push foward Tableaunoir in order to create presentations. The philosophy would be as follows.

• No coding because it is user-friendy enough (so it will not be like LaTEX/Beamer)
• Animations: replay a drawing (to be implemented) + move magnets
• Changing slides: by deleting the board :)
  What do you think?
