   *
   *     "Spectacular stunt, my friends, but all for naught. Turn around
   *      please. Ha. What a pity. What a pity. So, Princess, you thought
   *      you could outwit the imperious forces of...."

   *     "You idiots! These are not them. You've captured their stunt
   *      doubles! Search the area. Find them! Find them!"
   *
   * StuntDouble is a very strange idea.  A StuntDouble stands in for
   * some object that can be manipulated by the Integrators or
   * Minimizers.  Some of the manipulable objects are Atoms, some are
   * DirectionalAtoms, and some are RigidBodies.  StuntDouble
   * provides an interface for the Integrators and Minimizers to use,
   * and does some preliminary sanity checking so that the program
   * doesn't try to do something stupid like torque an Atom (The
   * quotes above are from Spaceballs...)
