[lfziifrc] Double tap

A single button interface could provide binary input by distinguishing single pushes and rapid double pushes.  (This of course makes impossible rapid single pushes.)  This could be extended to triple pushes, etc.  Very similar to phone spelling.

Morse code distinguishes between short and long, but I am less confident technologies like touchscreens can reliably distinguish them.
