d228784c39 Don't pass the automaton to enumerate_cycle and is_weak_scc. 
The scc_map knows the automaton already.

* src/tgbaalgos/cycles.cc, src/tgbaalgos/cycles.hh,
src/tgbaalgos/isweakscc.cc, src/tgbaalgos/isweakscc.hh: Simplify the
interface.
* src/tgbatest/ltl2tgba.cc: Adjust calls.

92e37998b2 Better documentation for the cycle enumeration algorithms. 
* src/tgbaalgos/cycles.cc, src/tgbaalgos/cycles.hh,
src/tgbaalgos/isweakscc.hh: Improve .doc
* src/tgbaalgos/isweakscc.cc (weak_checker::cycle_found):
Scan the DFS backward so we only look at the cycle part.
