示例1: shapeInit

The SLRefGroup::shapeInit checks the validity of the referenced node. To avoid
endless loops a refShape node is not allowed to refShape its ancestors. An
ancestor of a refShape node is group node followed along the previous pointers
with lower depth than the depth of the refShape node.
