Added new subclass with unified view based on SpDiffPresenter

[CarolinaMelendez]

SpDiffPresenter displays a split view. So I added a sub-class that displays a unified view called SpDiffUnifiedPresenter

but this will not work.
You need to include StUnifiedDiffChangesMorph in the correct place.
(and call it SpUnifiedDiffChangesMorph) :P

Hi @estebanlm thanks for the review. I see I need to learn more. By the correct place of StUnifiedDiffChangesMorph you mean it should be in the same package together with DiffMorph ?

I would like to add that StUnifiedDiffChangesMorph is not a class I created, I just reuse that class because it already has the unified view there. I don't think I have the right to move the package. There is not a another way that make it works or is necessary to move the the location of StUnifiedDiffChangesMorph ?
