coarse_groups : Iterable of 2-tuple
The energy groups of interest - a list of 2-tuples, each directly
corresponding to one of the new coarse groups. The values in the
2-tuples are upper/lower energy groups used to construct a new
coarse group. For example, if [(1,2), (2,4)] was used as the coarse
groups, fine groups 1 and 2 would be merged into coarse group 1
while fine groups 3 and 4 would be merged into coarse group 2.
