More accurately, it's a fancy way of doing averaging. When your new
bins are related in the right way to your old bins, calculating the
right average for the new bins is relatively simple. When they aren't,
it can be highly non-trivial, and flux-conserving algorithms cope with
some of the problems that can arise.
