1) I modified the BOUT reader to display the absolute value of the variable
   when displaying a variable on the diverter. The release notes were updated
   with a description of the change. 

2) I modified the BOUT leader to display the upper diverter with a two X
   grid. The release notes were updated with a description of the change.

3) I modified the BOUT reader to eliminate the grid above the upper X point
   when working with a grid with two X points. The release notes were updated
   with a description of the change.

4) I modified the BOUT reader to include all of the lower diverter. The
   release notes were updated with a description of the changes.
