This is an API wrapper around the Cephes library.

The inspiration for doing this came from Evan Miller's blog post, Statistical Shortcomings in Standard Math Libraries (And How To Fix Them).

I've used the sources from the Perl library, Math-Cephes, to get the Cephes library to build on macOS 10.12. Not sure how to go about modifying the code to have it buildable on ARM, so if you have any ideas, a PR is welcome.

Next step is to port the Math-Cephes test cases to XCTest-based Unit Tests. Here's the list of test files from Math-Cephes:

• bessels.t
• betas.t
• cmplx.t
• dists.t
• elliptics.t
• explog.t
• fract.t
• gammas.t
• hypergeometrics.t
• hypers.t
• mat.t
• misc.t
• new_cmplx-2.t
• new_cmplx.t
• poly.t (Currently working on this one)
• style-trailing-space.t (Can't test in Perl. Not going to attempt in Objective-C)
• trig.t
• utils.t

I've also taken the liberty to put the Cephes Math C functions into their own "namespace". Currently the vast majority of the functions are prefixed by the cfs_ prefix. The intention here is that when the Objective-C / Swift API wrappers are built, all possible collisions with the math.h library will be avoided. NOTE: Most, but not all functions have been namespaced.

PRs are welcome.
