  \class SoNodeList SoNodeList.h Inventor/lists/SoNodeList.h
  \brief The SoNodeList class is a container for pointers to SoNode objects.
  \ingroup nodes

  As this class inherits SoBaseList, referencing and dereferencing
  will default be done on the objects at append(), remove(), insert()
  etc.
