OK, and now including a simple colour legend on top. Thanks @wowgetoffyourcellphone ! R28 is for Version 0.28 and R29 for the new SVN version 0.29 (nightly build). Looks like the internal mechanisms changed.  There is also a little user and maintainer documentation. modiomod-documentation.md modiomod-r29.zip modiomod-r28.zip
