    sccfilter: implement a new version of tgba_digraph · 13673a14
    Alexandre Duret-Lutz authored
    The new version currently supports removal of useless state as well as
    removal of acceptance sets from non-accepting SCCs (the two versions).
    It does not yet support simplifation of acceptance sets and removal of
    suspendable formulae.  However the design, using filters that are
    composed before being applied, should make it easier to implement.
    * src/tgbaalgos/sccfilter.cc, src/tgbaalgos/sccfilter.hh: Implement
    the new scc_filter and supporting classes.
    * src/tgbaalgos/simulation.cc, src/tgbaalgos/simulation.hh: Use it.
    The simulation now always return a tgba_digraph.
    * src/tgbatest/sim.test: Adjust.
