Shadow casting implementation

In order to create the shadows for the player to move through, I needed to implement a shadow casting algorithm. This video explained it quite well, implemented in C++. I decided to give it a shot, and although it took a while, I got there in the end. Overall I'm pretty happy with how it turned out, but I haven't figured out how to apply the final optimization step yet, I'm still working on it.

Below is a demonstration.
