     We are experimenting with different methods for dealing with
     components of graphs (such as subgraphs). One way to do this is to
     assign a unique identifier to each component of a graph. Subgraphs
     then need only retain the identity of the graph and the ids for
     the selected components.

     The intention is to have these be internal to the graph package
     and they will likely not be exported. They are primarily for
     housekeeping purposes.

     There are currently two ways of assigning IDs. One relies on the
     'Ruuid' package the other on integers. In the long run only
     'Ruuid' will be supported.

     startids(x)
     newID(cur)

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

       x: an integer to start numbering components from.

     cur: an integer, the current index

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

     'startids' sets the starting value for the sequence. It has

     These are used basically just for side effects and internally.
     Users should not use them. If you want uuids please use 'Ruuid'
     directly.
