/**
 * \brief Helper macros for analyzing name.femtoDst.root files using FemtoDstAnalyzer.C
 *
 *  This macros takes inFileName argument with a femtoDst.root file
 *  or with a list of files (name.lis or name.list). It sets _VANILLA_ROOT_
 *  (necessary for standalone mode), loads pre-compiled libStFemtoDst.so
 *  (from StFemtoEvent), compiles and executes a text
 *  FemtoDstAnalyzer.C macro with passing inFileName to it, and
 *  cleans up the directory from the compilation products at the end.
 *
 *  Some details:
 *    inFileName - is a name of name.femtoDst.root file or a name
 *                 of a name.lis(t) files that contains a list of
 *                 name1.femtoDst.root files.
 *    NOTE: inFileName should contain either /absolutePath/inFileName
 *          or /relative2currentDir/inFileName
 *  It is assumed that FemtoDstAnalyzer.C is placed in the same
 *  directory where the RunAnalyzer.C is stored.
