77     * StuntDouble is a very strange idea.  A StuntDouble stands in for
78     * some object that can be manipulated by the Integrators or
79     * Minimizers.  Some of the manipulable objects are Atoms, some are
80     * DirectionalAtoms, and some are RigidBodies.  StuntDouble
81     * provides an interface for the Integrators and Minimizers to use,
82     * and does some preliminary sanity checking so that the program
83 <   * doesn't try to do something stupid like torque an Atom
