 *
 * Main program to evaluate quality data from data base.
 *
 * The evaluation of the data quality is based on the following procedure.\n
 * For each data taking run, the script JQAQC.sh is executed which produces a set of values. 
 * The values are subsequently uploaded into the database in table "runsummarynumbers". 
 * This table is a general purpose table for any value related to some data taking run.
 * With this application,
 * the QA/QC data are consistently downloaded from the database;
 * evaluated according some formula and
 * tested against a validity range.
 * The formula and validity range are referred to as a condition and can be specified with option -Q.
 * Each condition has an optional weight (defaut is 1).
 * The normalised total weight is used to define an overall quality, ranging from 0 = worst to 1 = best.
 * There is also the possibility to specify a veto (option -V),
 * which is similar to a condition but only the number of vetoes is counted.
 * The overall quality and the number of vetoes can be used to accept or reject a data taking run.
 *
 * By default, a list of the run numbers, the overall weight and the number of vetoes is printed.
 * If a ROOT file is specified for the output (i.e.\ filename extension is "root"),
 * a file is written which contains a histogram for each condition and each veto; some summary histograms and a ROOT n-tuple.
 * If an ASCII file is specified for the output (i.e.\ filename extension is "txt"),
 * a text file is written which can subsequently be used as input file.
