Use ODA_2018_ANSWERS to specify ODA remapping

Added the new run-time parameter ODA_2018_ANSWERS to recover the answers from the previous version of the code, which did not supply properly dimensional rescaled minimum thicknesses for the remapping calls in the ODA driver.  When this is set to True, all answers are bitwise identical.
