0028 //! defines a Group node of VRML specifying group properties.
0029 //! This node defines the base class for all group nodes. Group is a node that
0030 //! contains an ordered list of child nodes. This node is simply a container for
0031 //! the child nodes and does not alter the traversal state in any way.
0032 //! During traversal, state accumulated for a child is passed on to each successive
0033 //! child and then to the parents of the group (Group does not push or pop traversal
0034 //! state as separator does).
