/*

  !AIC KEY - Reposition code is called throughout this file.  What this does is
  pick a new direction close to the target direction (or away from the target
  direction if running away) and a distance to move in and tries to move there
  with move_scan(). If it hits something it will try again.  No movement is
  actually acomplished here. This is just testing for clear paths to move in.
  Location variables that are changed are saved and reset.  FindNewAngle() and
  move_scan() are two routines (above) that go with this.  This is definately
  not called every time through the loop.  It would be majorly slow.
