If two feature edges are close, allow points to be inserted on both edges if
the angle is large enough

pairGAMGAgglomeration: Support reverse cell-scanning without reversing the order of the generated agglomeration
Gives better cache coherency

This is more consistent with the faceArea agglomeration and generates more reliable agglomerations.

such that the sum of the values in the fines cells is equal to the value in the coarse cell
