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

     computed edge connectivity and min disconnecting set for an
     undirected graph

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

     edgeConnectivity(g)

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

       g: an instance of the 'graph' class with 'edgemode' undirected

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

     Consider a graph G consisting of a single connected component. The
     edge connectivity of G is the minimum number of edges in G that
     can be cut to produce a graph with two (disconnected) components. 
     The set of edges in this cut is called the minimum disconnecting
     set.

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

     A list: 

connectivity: the integer describing the number of edges that must be
          severed to obtain two components

minDisconSet: a list (of length 'connectivity') of pairs of node names
          describing the edges that need to be cut to obtain two
          components
