[rzcjbyla] Dasher CPU

The Dasher interface is spectacular, but also interesting that it requires considerable computational power (compared to a keyboard) to run it, making it a truly modern interface.

I like how it incorporates information theory.

Make the direction be up instead of to the right, so as to be able to keep an eye on the already "typed" text (an option already in preferences). Make the already typed text be justified so the cursor remains at the center of the last line.
