In contrast to smallpt, it is supposed to be readable and thus, somewhat
The path tracer supports diffuse, specular, transmissive and glossy surfaces,

not propperly cosine weighted at the moment.
There is also no scene graph implementation or any means of accelerating ray
The path tracer is split into multiple modules. Scene descriptions are loaded
from a textual description.
