 * Run the QATrender
 * 
 * The QATrender is run over the list of files (runs) to produce the
 * file <tt>trending.root</tt> which contains a TTree of QA
 * information - one entry per run.  
 * 
 * The QATrender will also produce two files per run: 
 * 
 * - <tt>index.root</tt> which contains TCanvas objects of
 *   the finished plots.
 *
 * - <tt>index.pdf</tt> which is a PDF of the TCanvases
 *   mentioned above.
 *
 * @param input  Input file
 * @param type   Data type (data or sim)
 * @param year   Year 
 * @param period Period (e.g., LHC10h)
 * @param pass   Pass (e.g., pass1, cpass1, passMC)
 * @param runNo  Run number
