_D_e_s_c_r_i_p_t_i_o_n:

     Provide short-hands for vertex set and edge construction.

_U_s_a_g_e:

     v(...)
     u(...)
     d(...)
     r(...)

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

     ...: unique vertex identifiers (should be characters for 'v' and
          strictly positive integers for 'u','d' and 'r')

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

     Function 'd' builds a directed edge from tail to head, function
     'r' builds a directed edge from head to tail.

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

     Function 'v' returns an object of  class '"vertexSet"'. Function
     'u' returns an object of  class '"undirectedEdge"'. Both functions
     'd' and 'r' return an object of  class '"directedEdge"'.

_A_u_t_h_o_r(_s):

     Jens Henrik Badsberg, Claus Dethlefsen, Luca La Rocca

_S_e_e _A_l_s_o:

     'vertexSet-class', 'undirectedEdge-class' and
     'directedEdge-class'.
