Add stripe rectangular display #54
Description
Add stripe display for rectangular grids. This will show the coordinates for points along diagonal stripes that move up and right from their starting positions. Using the double alphabetic grid with a checker display where n is 17 shows this pattern. The number of stripes to show is a setting that will be adjusted with the "chicken stripe number_small". Possibly add double stripe display that also has stripes going right and down from their starting positions.
