28//! defines a Group node of VRML specifying group properties.
29//! This node defines the base class for all group nodes. Group is a node that
30//! contains an ordered list of child nodes. This node is simply a container for
31//! the child nodes and does not alter the traversal state in any way.
32//! During traversal, state accumulated for a child is passed on to each successive
33//! child and then to the parents of the group (Group does not push or pop traversal
34//! state as separator does).
