Removing dumb comment.
Updating really old comments in  header file.
Optimized simplex and perlin noise functions. Renamed a bunch of functions inside noise class for better clarity. Also added some more options in texture and material handler for different types of noise.
Cleaned up a little more in marching cubes class.

Made generatevegetation function in renderer cleaner and you can now control the amount of vegetation and the LOD levels with a float variable (vegetationCount).

Added function to create procedurally generated "material" textures with the use of simplex noise and a user defined color spectrum.
