    some things that need to be done:

    - file paths should be changed in scripts that call other scripts.  for now,
      we've made it so that scripts are called from the current directory
      (./<SCRIPT>).  However, this needs to be changed, particularly for the
      snapshots-related scripts.  This is because these scripts cd into 
      the subjects directory before taking snapshots.  So other scripts will
      need to be called with their full paths (rather than ./)

    - make sure status log checker works for -autorecon2-cp and -autorecon2-pial      flags 

    - the output path for the snapshots html file needs to be corrected...

    - make output file checking script able to take filelists of output files in different orders
    
    - make logs in SUBJID/scripts/ foreach checking script

    - summarize the logs of -details and -summary, across subjects (eg. a spreadsheet)

    - add greconversion into main recon_checker script

    - output ENV variables somewhere
