Changed the public effect step method in StripEffect to be step() instead of step_effect()
Fixed broken test that should have been fixed like 30 commits ago, oops?
Abstracted out the parts of LedStrip that work on the pixels to a parent object
Added function to PixelList to return list of RGB tuples
Made PixelList iterable by returning an iterator of its pixels
Added functionality to StripEffect to transition smoothly between two steps in an effect, making slower effects look much better and less jerky
Updated to demonstrate the difference of the smoothing effect of StripEffect
