Version 2.3 of Koalog Constraint Solver

Release Notes: This version now includes a Local Search solver useful for solving huge problems when exact methods are too slow. Exact (Constraint Programming) and approximate (Local Search) methods are well integrated in the new hierarchy of solvers. This version is now supported on Java 5.
