[fsa] Corrections to README

16 Feb 2005

      The top level README file has a short C++ example of using the
library.  It contains three bugs:

* Must use "f->" instead of "f." everywhere
* f->setInputAlphabet() wants ConstAlphabetRef instead of (StaticAlphabet*)
* It seems that setId() must be called for each state manually.

Here is the correct (hopefully) version of the code:

        using namespace Fsa;
        StaticAutomaton *f = new StaticAutomaton;
        f->setType(TypeAcceptor);
        f->setSemiring(TropicalSemiring);
        StaticAlphabet *a = new StaticAlphabet();
        f->setInputAlphabet(ConstAlphabetRef(a));
        State *sp1 = new State(), *sp2 = new State(StateTagFinal);
        sp1->setId(0);
        sp2->setId(1);
        sp1->newArc(sp2->id(), f->semiring()->one(), a->addSymbol("a"));
        sp2->newArc(sp2->id(), f->semiring()->one(), a->addSymbol("a"));
        f->setState(sp1);
        f->setState(sp2);
        f->setInitialStateId(sp1->id());
        ConstAutomatonRef fr = ConstAutomatonRef(f);
