implement machine independent math functions?

[dtamayo]

Several effects need math functions (trig functions, pow, log) that are not platform independent in the C99 standard. It would be nice to implement machine independent functions even if they're slower than the standard functions so that we can rely on REBOUNDx also being machine independent. Here's a starting point

though at least some of the functions are meant for computer graphics and are low accuracy

I agree, that would be a good thing to add. But that library hasn't been update in many years.
