I added csvimport.m . Also, I moved the Dice calculation to within the main 'kernel' "fast_temperature_obj_fxn_sanity.m" .
I got the code running with the Dice calculation within fast_temperature_obj_fxn_sanity.m .

Also, hist_plotting.m works with dlmread instead of csvimport.m .
I untracked csvimport.m coz I don't need it anymore.
