Fixed a (potential) exception safety bug in class MIP_Problem.
Added an helper class (implementing RAII technique) to safely relax a MIP
problem into an LP problem and ensure that integer variables are restored
even in the presence of exceptional execution paths.
Improved interface (and a few comments) for private methods dealing with
MIP optimization and satisfiability.
