A = CR Factorization #18

I’ve read through the debate about adding rref to Base. One of the arguments for keeping it around was pedagogical, as it is instructive in teaching Linear Algebra. I appreciate it finding a home here in RowEchelon.jl, as I am taking several of Gilbert Strang’s MIT Linear Algebra classes including 18.065 and his most recent. In them rref is used extensively.

In these classes, he has been extolling the virtues of the A = CR factorization. He admits it is not intended for numerical computation, but that it is useful for teaching purposes. It not a complicated function, but I have implemented it. Is it something that would find a home here, especially that almost all of it is based upon rref_with_piviots? If so, I can provide a PR

Yes, if the code is simple, that could be a good fit for this package
