Assets Voronoi Based Map Generator

I've created a map generator that uses a list of Vector2 points to generate a voronoi diagram, and then uses that as an input to generate a map graph and terrain mesh. I've released the code onto GitHub.

At the moment it takes 1,137ms to generate a map with 2764 nodes, so I'd quite like some feedback on how to improve the performance. Also I'd like to peturb the rivers when they're drawn onto the texture, but I'm not sure how to best proceed with that.
