Need to improve function 'crc_USwL.m'

[ChristophePhillips]

It's not advisable to pass the 'job' structure (from matlabbatch) directly to a routine as a single input!
There should be a 'run' function to collect the matlabbatch input and reformat them for the exec routine...
-> set @https://github.com/CyclotronResearchCentre/USwLesion/blob/master/crc_USwL.m with more explicit input
