Run a fileset scan. This populates the maps m_dirs and m_file, by scanning the directories specified in the map m_Roots. Firstly mark all existing files (those in m_dirs and m_files) for delete before a run. Then during the run the new files will be marked as CREATE and existing files either as MODIFY or NOACTION. Arguments: None
