Working on this option now. After looking at it, removing the binary
operator- seems rather harsh... if you know that a number is larger than
what you're subtracting from it, it would just be irritating. But I'll
definitely add the absdiff function (maybe named "difference"?), then
the developer using the library can decide which to use for himself.
