Modified files:
src : Polyhedron.cc
Log message:
Corrected a bug in poly_difference_assign(const Polyhedron& y).
No longer ignoring the equality constraints of `y'
(the bug was affecting both C and NNC computations).

Modified files:
src : Polyhedron.cc
Log message:
Corrected a bug in Polyhedron::operator=(...).
When assigning to *this a polyhedron declared to be empty,
we now call set_empty() to also clear the constraint and generator systems,
therefore enforcing the corresponding invariant.

Modified files:
tests : Makefile.am
Added files:
tests : polydifference2.cc
Log message:
Added a new test showing two bugs:
- the assignment operator on Polyhedron breaks the invariant saying that
an empty polyhedron has a constraint system with either no rows or
a single unsatisfiable constraint;
- the current implementation of poly_difference_assign() is wrong in
that it disregards equality constraints.
