-- Description: Wave option file child package doing the link between the
-- design and the other wave option packages.
-- Provides functions to find in the tree which signals are to be
-- displayed or not.
-- When State = Display_Tree, it reads the tree created after
-- parsing the wave option file and filters signals accordingly.
-- When State = Write_File, it calls File.Update_Tree to create
-- the tree from the design tree and write the signal paths of all
-- the design to a new wave option file.
