bml_sync_check

 BML_SYNC_CHECK loads files in a synchronization roi table into praat

 Use as
    bml_sync_check(cfg)

 cfg - configuration structure
   cfg.roi - roi table with additional vars 'session_id','session_part',
            'filetype','sync_channel','sync_type','chunk_id'. Contains 
            a coarse alignment of the files, normally inferred from the
            OS 'Date-Modified' metadata.
   cfg.praat - logical: should synchronized files be opened in praat for
   cfg.ft_feedback - string: default to 'no'. Defines verbosity of fieldtrip
           functions
