Adding a generic mathematical library

[Christopher Dimech <dimech@gmx.com>]

Emanuel, looking at calc.el you will find

;;   Provide a better implementation for math-sin-cos-raw.
;;   Provide a better implementation for math-hypot.

You can focus on these two things so you can provide us with better
implementations of those two things.  Together with the necessary
framework for extension and for use by calc.
