This class represents a node owned by Assoc2dConstraintGroup. Usually a node is connected with multiple other nodes and the connection between two nodes is not directed. 

A ConstraintGroupNode object should always be created and deleted through higher level APIs and the memory pointed by it is internal held and should never be released by user directly.
