Examples of solver.variables.SetVar

solver.variables.SetVar
A Set Variable is defined by a domain which is a set interval [kernel,envelope] The kernel is the set of elements that must belong to every single solution. The envelope is the set of elements that may belong to at least one solution.
One must notice that in this context, a VALUE of the variable is a set of integers. @author Charles Prud'homme, Jean-Guillaume Fages @since 15 nov. 2012
