Added some debug information. Fixed the duplicate debug waypoint error, box indices should be ok. However, I think there is a bug with getting boat distances. Will look into it. Boat seems to always be going south once stationkeeping is initialized.
Got most of the GUI working, with the exception of exiting the Box. I've traced it to a bug in the function: calculateHeadingForExit, where I think None is returned to target. This is a problem because target, if none, crashes for adjustSheetsForExit. I will inspect how the original version avoided this problem.
