/**
 * Node behaviour for initial node.
 * Initial node is a "virtual" node added by bonita.
 *
 * The default behaviour is a wait state.
 * The execution waits for a signal to really start the instance. This way,
 * the method that created the instance can update some values in the instance
 * (e.g. execution to signal on completion for a subflow instance) before the
 * execution is really started.
 *
 * The instance is recorded as created only after this activity has been signaled.
