make a config file for FELsource

[samoylv]

FELsource script requires too many command line options.

Configuration file needed, as it is implemented for diffr module (maybe without recursive usage $CONFIG)

if [ "x$MODULE" == xdiffr ] ||  [ "x$MODULE" == xs2e ]  ; then
    cd $ROOT ;
    CONFIG="/data/S2E/modules/simulation_LP_5kev_9fs_2NIP_EMC/diffr/diffr_params_SingFEL_multi"
    echo $CONFIG $PROJECT $CONFIG
    $CONFIG $PROJECT $CONFIG
     ...
    # Perform diagnostic
    python /data/S2E/modules/diffr/diagnostic_singfel.py
