Grammalecte  Check-in [29e54c7426]

        This code is inspired from Steve Hanov’s DAWG, 2011. (http://stevehanov.ca/blog/index.php?id=115)
        We store suffix/affix codes and tags within the graph after the “real” word.
        A word is a list of numbers [ c1, c2, c3 . . . cN, iAffix, iTags]
        Each arc is an index in this.lArcVal, where are stored characters, suffix/affix codes for stemming and tags.
        Important: As usual, the last node (after ‘iTags’) is tagged final, AND the node after ‘cN’ is ALSO tagged final.
