  * This class is used by the TreeTable component to flatten a given Tree structure

  * so that it can be represented in an html table.

  * 

  * A Tree is nested, an html table is flat and this class represent each node of the

  * tree, but without nesting. The TreeTable component can then convert a Tree structure

  * (each Tree can contain other Tree childs) into a list of FlattenedTree objects.

  * The FlattenedTree still remember the position of the node in the original tree  in order

  * to render the tree correctly in html (reference to javascript used

  * by TreeTable component for details).
