struct Multigroup_D_and_sigR
For both WGDSA and TGDSA use, we define this simplified data structure to hold multigroup diffusion coefficients and removal cross sections only for the relevant groups. E.g., for WGDSA it will only hold the cross sections for the groupset, and for TGDSA there will only be one group (All groups collapsed into 1).
