     This creates a data structure describing the S4 class hierarchy
     informaion in a suitable format for 'link{createInheritanceTree}'
     to process and create a visual display of the relationships
     between the classes.

     getS4ClassHierarchy(classes = getClasses())

_A_r_g_u_m_e_n_t_s:

 classes: a character vector giving the names of the classes of
          interest. By default, all session-level classes are used. One
          can specify a subset of this list, or entirely different
          class located in another package/environment.

_D_e_t_a_i_l_s:

     This is a simple iteration over the class names that adds each
     class to a its ancestor's list of child classes.

_V_a_l_u_e:

     A list with an element for each of the classes in 'classes' and
     any parent or base classes that they directly or indirectly
     descend from. Each element, say A, is a simple character vector
     giving the names of the classes that are directly derived from the
     particular class, A.
