Bug fixes:
* The degen-lcache=1 option of the degeneralization algorithm (which
is a default option) did not behave exactly as documented: instead
of reusing the first level ever created for a state where the
choice of the level is free, it used the last level used. This
caused some posterior simulation-based reductions to be less
efficient at reducing automata (on the average).
