*
* NAME
* BufferNode -- Class to maintain the tree of bufferred elements
*
* FUNCTION
* One BufferNode object represents a bufferred element in the document
* wrapper component.
* All BufferNode objects construct a tree which has the same structure
* of all bufferred elements. That is to say, if one bufferred element is
* an ancestor of another bufferred element, then the corresponding
* BufferNode objects are also in ancestor/descendant relationship.
* This class is used to manipulate the tree of bufferred elements.
