 |   $Revision: 1.1.1.1 $
 |
 |   Description:
 |      Defines the SoNodeKitListPart class. 
 |      It behaves sort of like a group to the outsider, but it only allows
 |      certain types of nodes to be put beneath it.
 | 
 |      It contains hidden children, and is not derived from SoGroup.
 |      The addChild(), insertChild(), etc. methods all check that the
 |      new node is allowable beneath it.
 |
 |      The container node sits beteen the SoNodeKitListPart and the children.
 |      It's type is taken in the constructor, and must be derived from 
 |      SoGroup. By making the container an SoSeparator, SoSwitch, etc.,
 |      the SoNodeKitList can be made to encase its set of children in
 |      the appropriate behavior.
