Changed the eagle branch of bad-boids to create an eagle and starling subclass.
Removed the colour function from view_boids.py and made it a property of the eagle and starling classes in boids.py.
Made a number of changes in order to make the code work as intended. Firstly, seperation and seperation_sq were made functions of the boid super class. Secondly colour methods were added to both subclasses. Thirdly the boids class was changed so the code would work properly.
