Replace "iff" with "if and only if"

gmcgibbon · gmcgibbon · commit ffb87cad32c4 · 2021-01-20T20:16:22.000-05:00
iff means if and only if, but readers without that knowledge might
assume this to be a spelling mistake. To me, this seems like
exclusionary language that is unnecessary. Simply using "if and only if"
instead should suffice.
