Changes to groupr to fix an issue when doing automated processing on MF10 using an evaluation with an MF8 MT18 section that has a ZAP=-1 (new format for ENDF/B-VIII.0b6).
The solution is as follows: we now assign this case to the mfd number of 40000000.
While the issue appeared for automated processing of MF10, some code was added to allow users to specifiy this mfd number in the input file.
