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

     Given the regions where the events occurred and the cliques of the
     intersection graph the support of the cliques is computed. For
     each clique it is the intersection of the event time regions for
     all observations in that clique.

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

     BVsupport(intvlx, intvly, cliques=BVcliques(intvlx, intvly))

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

  intvlx: The event time intervals for one dimension. 

  intvly: The event time intervals for the other dimension. 

 cliques: The list of maximal cliques of the intersection graph,
          optionally. 

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

     An m by 4 matrix containing the corners of the intervals of
     support for the maximal cliques of the intersection graph
     corresponding to the first two arguments to the function.
