Initial import of dasher, version 3.2.3:

Dasher is an information-efficient text-entry interface, driven by natural
continuous pointing gestures.  Dasher is a competitive text-entry system
wherever a full-size keyboard cannot be used - for example:
- on a palmtop computer
- on a wearable computer
- when operating a computer one-handed, by joystick, touchscreen, trackball,
  or mouse
- when operating a computer with zero hands (i.e., by head-mouse or by
  eyetracker)
