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