Refactor class position of ChaosGameDescription, ChaosCanvas and ChaosGameFileHandler under MVC-pattern.

Made working solution for description combo box. Still need to add different descriptions and potentially replace the radio button system entirely.

Changed the way the fractal image is generated and displayed such that a graphics context and Canvas class is used, and added button to show and hide the sidebar.

Began implementing level of detail system by correlating the zoom level determined by chaos game image view with what subsection of the canvas should be populated with new points.
