/// REVISION HISTORY:
///
///  07/2014 : F. Descamps - First version,  only TELLIE now
///
///  \detail  This processor checks the PCA-TELLIE quality of data
///           and outputs .png files (which can be used on
///           the snoplus monitoring page) and a .ratdb file that
///           summarizes the run quality.
