CurrentHypothesisViewer should visualize progress status, so as to be useful with iSS
(currently, words/phrases are shown as they are added and there is no feedback on progress; at the same time, this functionality is already implemented via update listeners in the synthesis demos. it should not be hard to add the same behaviour to CHV.)
might be a good idea to use this advanced CHV in the synthesis demos then.
this has been fixed, currenthypothesisviewer now uses the IU's progress field to show the IU's .. well .. progress.
