/*
 *# Parameters:
 *#    saveApeToASCII -- Do we write out an APE text file?
 *#    saveComposites -- Do we write APEs for composite detectors?
 *#    saveLocalNotGlobal -- Do we write the APEs in the local or global coordinates?
 *#    apeASCIISaveFile -- The name of the save-file.
 *#    readApeFromASCII -- Do we read in APEs from a text file?
 *#    readLocalNotGlobal -- Do we read APEs in the local or the global frame?
 *#    readFullLocalMatrix -- Do we read the full local matrix or just the diagonal elements?
 *#                        -- Always write full matrix
 *# Full matrix format: DetID dxx dxy dyy dxz dyz dzz
 *# Diagonal element format: DetID sqrt(dxx) sqrt(dyy) sqrt(dzz)
 *#    setComposites -- Do we set the APEs for composite detectors or just ignore them?
 *#    apeASCIIReadFile -- Input file name.
 *# Also note:
 *#    process.AlignmentProducer.saveApeToDB -- to save as an sqlite file
 *# and associated entries in _cfg.py
