   At least N elements of Vars have the value V.

Arguments
   +N                  An integer
   ?Vars               A collection (a la collection_to_list/2) of domain variables or integers
   +V                  An integer

Type

Description
   This constraint ensures that at least N element of Vars have the value V.
   As soon as some domain variable from the collection is updated, this
   constraint is woken and it checks if the constraint is still satisfiable
   and if so, if it is already satisfied or not.


Fail Conditions
      Fails if less than N elements of Vars can take value V.
