new layouts
added new layouts (not so promising unfortunately)
changed to io module to gain some speed. Not sure about success anyway
fixed percent computation. Now it shows the distance to the best scored layout
some new layouts just trying to optimize within the current view of what is good performance. Starting to doubt whether this view is correct. In any case, a somehow brief study should be performed on triads. It is possible that some triads are far more frequent than some symbols and final layout should make them easy to type
added tri-tuples
reconsidered frequencies
