Photon Mapping
For this program I attempted to use the photon map implementation from
Jensen's book 'Realistic Image Synthesis Using Photon Mapping'.
I had to play with the scaling power of the photons and the number of
photons I emitted into the scene. Alot of these pictures get progressively
better as I tweak these parameters. My algorithm used only a point light source
and not the square light source from the data set. I think this is why the images show the
highest concentration of photons off center on the ceiling and towards the
back left wall. I plan to better this implementation over the break.

Photons: 8 million, scaled power: I don't remember

Photons: 6 million, scaled power: 9000

Photons: 8 million, scaled power: 5000

Photons: 4 million, scaled power: 7000

Photons: 8 million, scaled power: 7000
