 * DESCRIPTION:
 *
 * The PickMode object which allows a pointer to be used to create new 
 * geometrical monitoring labels.  This particular version is used only for
 * adding molecular labels, i.e. Atoms, Bonds, Angles, and Dihedrals.  As
 * more atoms are selected, they are remembered until enough have been picked
 * to create the relevant label (i.e. 3 atoms to create an Angle label).
