Fixup the case study script

New features: - Checks arguments - Checks that we're root first - Checks if task launches succeed - Checks that a case study is not already running Fixes: - Removes invalid uses of sudo - Fixes use of ',' rather than ';' in resctrl specification - Fixes PID determination - Always launches Level-C tasks as asynchronous threads Additionally converts the whole file to only use spaces and to be directly executable.

/*================================================================
* function w = affinityic(emag,ephase,pi,pj,subgrid,nrSubgrid,ncSubgrid,subpi,sigma)
* Input:
*   emag = edge strength at each pixel
*   ephase = edge phase at each pixel
*   [pi,pj] = index pair representation for MALTAB sparse matrices, pi index in original grid, size(pj)=nrW*ncW+1
*   subgrid= index of the subgrid in the original image (first pixel's index is one!)
*   [nrSubgrid,ncSubgrid]= number of rows et colums of the subgrid
*   subpi = pi but with index in subgrid
*   sigma = sigma for IC energy
* Output:
*   w = affinity with IC at [pi,pj]
