/*
 * This analyzer will extract all fileblobs in the input edm/root file and
 * write them as files to the file system.
 *
 * It searches for the files in the vector of fileblobs that should exist on
 * the level of the run. Unique filenames for each file are generated based
 * on a formating directive in the output filename parameter.
 *
 * The operation is performed during the endRun phase.
 *
 * The original embedding of the (binary) files in the edm/root files can be
 * done with the corresponding module MillePedeFileConverer.
 *
 * For more info about the possible parameters, type:
 * edmPluginHelp -p MillePedeFileExtractor
