File: SortablePicture.h
Contains: Header file for the Sortable Picture abstract base class. This class is used as
a base for all sorting classes that sort pictures. Sorts that derive off this
class are only required to overide the Sort method to allow sorting of a picture.
the sort method should use the InOrder() method for comparing pixels and the
SwapPixels() method to swap two pixels, this also allows the base class to keep track
of Comparison and Swap counts.
