New function.
(LtlFormula::evaluate(const Bitset&)): Use the above function
internally.

`const'.
* main.cc (testLoop): Use autoconf-generated PACKAGE_VERSION
macro for displaying program version instead of including
version.h.
* src/Makefile.am: Remove redundant references to @LEXLIB@ (the
sources are independent of any external lexer library).

detection for jumps to undefined never claim labels.

of a parse error.

bug in the construction of the witness path in which the formula
should be evaluated when the witness path is extracted directly
from the original state space (i.e., when analyzing results
against the internal model checking algorithm).
