consequence.

minimized if translated by LaCIM, because the product of a
tgbabddconcrete automaton with another automaton (done during
WDBA-minimization) use the support conditions to speed things up.
This is motivated by the fact that sog-its used the low-level data

It was a mistake to try to overload And/Or LTL operator for these when
trivial simplification are performed. The reason is so simple it is
embarassing: And(f,1)=f is a trivial identity that should not be
applied with AndRat. E.g. AndRat(a;b, 1) is equal to 0, not a;b.
* src/ltlast/multop.hh, src/ltlast/multop.cc: Add the AndRat and OrRat
operators.

* src/ltlparse/ltlparse.yy, src/ltlparse/ltlscan.ll: Add parse
rules for LTL. This required passing the parse_error list
to the lexer, so it can report scanning errors when it reads
a number that does not fit in an unsigned int.

rational expressions. Also use {braces} to group rational
expressions.
* src/tgbaalgos/ltl2tgba_fm.cc
(ratexp_trad_visitor::ratexp_trad_visitor): Remove the possibility
to select the empty_word should act like true, and fix the rules

support AndNML.

Trivial simplifications rules (such as "FFa=Fa" or "x&1=x")
are performed any time a formule is instanciated.
* src/ltlast/constant.hh, src/ltlast/constant.cc
(true_instance, true_instance_): Declare the true_instance_ as a
static member, and move true_instance() into the .hh so it gets
inlined. Have true_instance_ as a class variable will ensure that
it is the first formula instantiated. Binop simplifications rely
on this to order arguments.
(false_instance, false_instance_): Likewise.
(empty_word_instance, empty_word_instance_): New method and static
member.
* src/ltlast/formula.hh (formula::formula): If max_count_ ever

This implementation of direct simulation was only working on
degeneralized automata, and produce automata that are inferiors to
those output by the new direct simulation implementation (in
tgba/simulation.hh) which can also work on TGBA. The delayed
simulation has never been reliable. It's time for some spring
cleaning.
