Revise paste WhipRobot

/*
Whip mechanics robot: 
uses tethered mouse feedback via motor impulse, and cord length to generate pseudo-random motion continuing from an initial motion. 
Possible improvements:
dont use delay, or dont interupt mouse feedback, or dont stop after initial start at 0,0 crossing.
   Initial start up is at 0,0, x,y +/-
works ok as is.
