| Returns `true` if and only if `*this` and `y` are different.

## Detailed Description

An iterator over a system of constraints.

A const_iterator is used to provide read-only access to each constraint contained in a Constraint_System object.

Example
  The following code prints the system of constraints defining the polyhedron `ph`:
  const Constraint_System& cs = ph.constraints();
  for (Constraint_System::const_iterator i = cs.begin(),
  cs_end = cs.end(); i != cs_end; ++i)
  cout << *i << endl;
