 * have the changeType() NodeCreated. You should not need to instantiate this class.
 * Usually you should be using one of its subclasses such as QNodeCreatedChange.
 *
 * You can subclass this to create your own node update types for communication between
 * your QNode and QBackendNode subclasses when writing your own aspects.
