Research direction

No file or test is named. Locate the SANS data-reduction entry point and compare the polarized workflow with the unpolarized SANS path, focusing on background subtraction and polarization correction order. Done means the background run is subtracted after polarization correction for the sample, with coverage for the corrected ordering.
