Addition of TOC code to handle very long header titles for toc-sections

For Statistics, some of the module titles are very long and are not wrapping well in the TOC.  Code was added to convert these elements to blocks and lay them out properly with module title header wrapping appropriately with text indent at section number (1.1).  

Along with this fix a solution was arrived at on how to display multi-line headers and still utilize the ellipsis (...) and associated page (target) links to display appropriately.
