cheat-sheet with cabbage keystrokes.

Hi,

I just put some nitty gritty code together to build an cheat-sheet out of the ergonomic bundle keystrokes.

Here are the code: https://gist.github.com/tonini/6345606

The output is like this: https://www.dropbox.com/s/c7edsoo5e23ehia/cheat-sheet.pdf

It's all just prototypal, but I would like the idea to build an cabbage keystroke cheat-sheet on the fly to give users a better overview about the cabbage key layout setup.

@senny @jone what do you think about this?

cheers
