      values.
      
      Before this change states were numbered using positive values and
      SCCs using negative values.  That meant the user had to work with
      negative values.  With this changes, the nonnegative values used
      to label SCCs can also directly be used as index in the scc_map_.
      
      * src/tgbaalgos/scc.hh (scc_map::scc_of_state,
      scc_map::cond_set_of, scc_map::acc_set_of, scc_map::states_of,
      scc_map::initial, scc_map::scc_type, scc_map::succ,
      scc_map::accepting): Adjust prototypes to take or return unsigned
      arguments.
      * src/tgbaalgos/scc.cc: Adjust prototypes of the above functions.
      (scc_map::build_map, scc_map::relabel_component): Number states
      using negative values, and SCCs using nonnegative values.
      (dump_scc_dot): Adjust to use nonnegative values.

      point in using a map since the SCC are numbered in sequence.
      
      * src/tgbaalgos/scc.hh (scc_map::relabel_component): Return the
      number of the SCC instead of taking it as argument.
      (scc_map::scc_num_): Delete this variable.  scc_map_.size() gives
      the same information.
      (scc_map::scc_map_type): Define using std::vector instead of
      std::map.
      * src/tgbaalgos/scc.cc: Adjust all uses.

      Implement these new functions.
      (dump_scc_dot): Display number of states, conditions and
      acceptance conditions, with VERBOSE is set.
      (build_map): Fill the new scc_map::scc::cond field.
