SoSFEngine — field containing a pointer to a engine

       This field maintains a pointer to an SoEngine instance, correctly maintaining its reference count.

       SoSFEngines are written to file as the engine they are pointing to. For example:

          mySoSFEngineField ElapsedTime {}

     is  an  SoSFEngine  field  named 'mySoSFEngineField', pointing to an SoElapsedTime engine. If the engine is
     used elsewhere, the regular DEF/USE instancing mechanism applies:

          anotherSoSFEngineField USE calculator

     is an SoSFEngine field that points to a engine named 'calculator' that was DEF'ed earlier in the scene.
