* Appear to have fixed displacement tracking
* Strain plotting or strain calculation is incorrect
* Flipped image that is plotted so axis directions of matrix indices line up with axis direction of image
* Changed quiver plotting to use "dot" as units so now the position and displacement is in units of pixels.
* Started putting displacement and strain plots on the same figure so they can be compared side-by-side
* Decreased subset spacing to get more tracking points
