This is for the "ll" function defined for quaternions and octonions. The
function returns the 1-norm of its argument. Does anyone know what the "ll"
name stands for? I finally figured out that "sup" (the infinity-norm) most
likely stands for "supremum". (BTW, "abs" is the 2-norm. The "norm"
function isn't actually in this system, despite the name!)
