  The sole function of SoNodeKit is to be just a placeholder for the
  toplevel initialization code for all nodekit-related classes.

  Initialize the nodekit system.

  been initialized.

  This method is also called from within SoInteraction::init(), as the
  interaction functionality in Coin depends on the nodekit classes.
