If node is not NULL and is not contained in Group then increment its

Otherwise return false. Scene nodes can't be added as child nodes.

<DD>set child node at position i.
|
|
return true if set correctly, false on failure (if node==NULL || i is out of range).
|
|
When set can be successful applied, the algorithm is : decrement the reference count origNode and increments the
|
|
reference count of newNode, and dirty the bounding sphere
|
|
to force it to recompute on next getBound() and returns true.
|
|
If origNode is not found then return false and do not
|
|
add newNode. If newNode is NULL then return false and do
|
|
not remove origNode. Also returns false if newChild is a Scene node.
