Added operator<<() for class PIP_Tree_Node, printing the subtree.
The output operator is based on public (non-virtual) method print(),
    which calls the protected (virtual) method print_tree() after properly
    setting up the needed arguments.

Date:   Mon Feb 22 14:04:27 2010 +0100
Changed interface for public method PIP_Solution_Node::parametric_values().
The new interface no longer requires the set of problem parameters as an
    input argument (which was error prone): rather, the set of parameters of
    the PIP_Problem is now automatically retrieved.
To this end, all PIP tree nodes are now provided by a pointer to the owning
    PIP_Problem object. Method PIP_Problem::OK() modified to check for well
    formedness of the solution tree and, in particular, check that all its
    nodes are marked as owned by the right PIP_Problem object.
Removed the no longer useful method PIP_Tree_Node::insert_artificials().
Corrected a typo in PIP_Problem::operator<<().
    Simplified interface of (internal) method PIP_Tree_Node::print_tree().
Added a FIXME regarding a potential exception safety issue.

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.

The generated Java tests now exploit the Test_Executor class functionality.
    Added an helper function to set global success flag and report success or
    failure if in noisy mode.
    NOTE: we are still (just) checking for the well formedness of the object
    (using method OK()), rather than checking if the computed result is actually
    the same of th expected one. However, due to genericity, it is quite difficult
    to precisely state expectations in these tests.

Method Box::refine_with is now based on (single step) constraint propagation.
    Method Box::propagate_constraints now also take as input a parameter for

    The constructor of a Box from a Polyhedron in polynomial time sets this
    parameter to a constant.

Improved code for wrap_assign() for grids for constant values.
If the value for a variable is already constant, and the constant is
    outside the range for the bounded integr type,
    then the outcome depends on the kind of overflow:
    - if `impossible', then the grid is set empty;
    - if `undefined', then the variable is set to take any integral value;
    - if `wraps', then the value is wrapped by the wrap_frequency
      to a value in the range for the bounded integer type.
Comments improved.
