Introducing Gould, a Karabiner layout.

This layout is highly inspired to @gabrielelana's amazing [Engelbart project](http://github.com/gabrielelana/engelbart),
with these few differences:

* key chords are more symmetrical chords (left and right hands use the same fingers)
* in order to aid (my) memory, different keys use different rows (that is: not all chords are on home row)
* it's more Emacs than vim focused

I'm currently experimenting with this layout. Hopefully, it will become a project itself.
Gould: Alt is mapped to key chords W+E and U+I
