Modified GalaxyFrame to be more modular - different init__() functions
MidpointDisplacement implements the Midpoint displacement algorithm for fractal landscape generation. Currently the code only outputs a 2D image with color mapped to height values (need to create 3D representation of topologies).

Fixed merge issues
Midpoint Displacement algorithm implemented to generate fractal landscapes.
Currently there is no way to view in 3D - only 2D with topology mapped to colors.
