## Detailed Description

An iterator over a system of congruences.

A const_iterator is used to provide read-only access to each congruence contained in an object of Congruence_System.

Example
  The following code prints the system of congruences defining the grid `gr`:
  const Congruence_System& cgs = gr.congruences();
  for (Congruence_System::const_iterator i = cgs.begin(),
  cgs_end = cgs.end(); i != cgs_end; ++i)
  cout << *i << endl;
