<PRE>
public void <B>removeChild</B>(int&nbsp;index)</PRE>
<DL>
<DD>Removes the child node at the specified index from this group node's
 list of children.

 <p>
 If the current child index order array is non-null, the element
 containing the removed child's index will be removed from the
 child index order array, and the array will be reduced in size
 by one element.  If the child removed was not the last child in
 the Group, the values of the child index order array will be
 updated to reflect the indices that were renumbered.  More
 formally, each child whose index in the Group node was greater
 than the removed element (before removal) will have its index
 decremented by one.

<DL>
<DD>Moves the specified branch group node from its existing location to
 the end of this group node's list of children.

 <p>
 If the current child index order array is non-null, the array
 is increased in size by one element, and a new element
 containing the index of the new child is added to the end of
 the array.  Thus, this new child will be rendered last.

<DD>Removes all children from this Group node.

 <p>
 If the current child index order array is non-null, then it is set to
 a zero-length array (the empty set).  Note that a zero-length
 child index order array is not the same as a null array in that
 as new elements are added, the child index order array will grow
 and will be used instead of the Group's natural child order.
