Early work on changing edge detection. Edge detection should not get confused when the subject bleeds into the side of the image.
Continued work on . The  module now finds the subject's edges with operations on the entire image array instead of working a row-by-row basis.
Edges are no longer stored as a sequence of namedtuples, but as numpy arrays per side of the image. The edges-to-text generator had to be changed to reflect this.
