docs

Hello!

So first and foremost, I must say that i'm terrible at documentation

What I have implemented so far:
-triangle, plane, sphere intersections
-directional light, point light (with falloff)
-shaders (allows custom shaders)
--specular
--diffuse
--ambient
--shadows (simple)
-orthographic, perspective rendering
-antialiasing
-BVH's for faster renders
-model imports using .off files (working for most simple models, no real api yet, must chage the name of the file in main.cpp)

to implement:
-more inline documentation, sorry about that
-some kind of percent notifier for when rays are being setup

dependencies:
-lippng
-libpng++ (c++ wrapper for libpng)
insall dependencies with apt install libpng++-dev on debian distros

renders folder contains some sample renders.
the program takes a the type of access to use, type "bvh" for BVH and anything else for linear. next is the amount of spheres. then the size of image.

adding objects requires you to create an object with new and add it to the scene. the scene::render() function will draw everything and output a png.

there shouldn't be any real memory leaks from the api, but if i find any i'll be sure to fix them

Thanks!
