Moments are centered at the center of the cell. For each of these moments I shift them to the lowest corner of the cell, where I know what the bounds of the integrals is (lower bound always zero, upper bound = dx^d dx^px dx^py dx^pz If the shifted moment is out of bounds, I bound it. The tolerance is about verbosity. If the moment is outside the tolerance then it gets included into a_bogusPowers. EBMoments do not get checked for maxvals.
