ScanLock was a test to see how much damage you could do
with a good scan routine.  This robot never moves.  It just
scans til it finds a target, then it clamps down.  If the robot
moves, I fall out of one level of the below While() loops, and then
relock on target.
This robot is extremely effective against any robot which moves at
speed=50 or less.  Faster robots move too quickly for my routine to
lock in.
