This routine was developed specifically as a counter-tactic for my
cybug, Reaper, (something which I'm proud of in a way). Reaper used move
next to an enemy, turn toward it, back away one space and launch a missile
into the enemy. Torque was the first cybug to counter this tactic by moving
out of Reaper's line of fire.
Torque checks for the situation by scanning the perimeter and finding
whether there are any enemies of mines. If there are neither then the enemy
is probably still alive and has moved away from Torque's perimeter.
Torque now jumps to a routine to perform the evasive action.
