There's a difference between referencing NR's descriptions of
algorithms and translating its code. I suspect that the functions in
stats.py, originally written by Gary Perlman, probably fall into the
latter category, but the others probably don't. Before pulling out
functions, it would be worthwhile to compare our implementations with
NR's to see if they in fact do look translated.
But do keep in mind that the algorithms are not copyrightable, and the
fact that there are only so many ways to implement said algorithms
correctly is fairly substantial protection for us.

enigma that is made terrible by our own mad attempt to interpret it as
though it had an underlying truth."
