No tools needed on OSX (and probably other systems)

For OSX, you don't need any tools. Just "open out.ppm" and you will see it in preview.

Thanks for the start on the tracer. I am also following the book, but plan on making a more go-flavored tracer, with objects that know how to do the intersections and such. We will see how far I get. :)

I wrote a raytracer in C about 20 years ago or more now. Graphics has always been a joy, but I don't use it in my work life.
