[Tutor] Sorting points on a 2D plane

[Robert Berman]

Kent and Alan,

Thank you both for providing me with tools I can use to develop the sort
portion of my algorithm. They are invaluable. I really appreciate Luke's
willingness to examine and advise on the full algorithm and once it is
written (only the function that determines distance between two points
is written and working) I will definitely add it to pastebin and ask for
your suggestions as well as the suggestions and comments from the group.

Again, thank you for your help.

Robert
