Description : Basically, turns 2 points into a rectangle.

This might not be the best way to do it, so don't get mad at me if I did it "Incorrectly".
And by the way, I suck at indenting/whitespacing.
...but this is public domain, so you can edit it all you want.
EDIT: JL235 helped me and made it simpler...
