Detailed Description

A constraint is the main modeling object. It provides two methods:
  - Post() is responsible for creating the demons and attaching them to
    immediate demons().
  - InitialPropagate() is called once just after Post and performs
    the initial propagation. The subsequent propagations will be performed
    by the demons Posted during the post() method.

    Creates a Boolean variable representing the status of the constraint
    (false = constraint is violated, true = constraint is satisfied). It
    returns nullptr if the constraint does not support this API.
