- Type Parameters:
    `V` - Variable
    `T` - Value

      public interface AssignmentConstraintContext<V extends Variable<V,T>,T extends Value<V,T>>
      extends AssignmentContext

  An extension of the simple `AssignmentContext` which is used by the `ConstraintWithContext` class. The notification methods assigned and unassigned are automatically called by the constraint whenever a variable of the constraint is assigned or unassigned respectively.

    - #### assigned

          void assigned(Assignment<V,T> assignment,
                        T value)

      Called when `ConstraintWithContext.assigned(Assignment, long, Value)` is called to update the content of the context.
      Parameters:
        `assignment` - current assignment (with which this context is associated)
        `value` - assigned value

    - #### unassigned

          void unassigned(Assignment<V,T> assignment,
                          T value)

      Called when `ConstraintWithContext.unassigned(Assignment, long, Value)` is called to update the content of the context.
      Parameters:
        `assignment` - current assignment (with which this context is associated)
        `value` - unassigned value
