+/* I didn't finish this program because I got stuck up on the first program trying to fix a bug so I ran out of time.
+My thinking behind this problem was making an object for each stain glass piece so I could send the object a
+location and have it return true or false. and from that I could run that each coordinate through two for loops of
+the largest x and y and determine whether each point was the right tint level. This is as far as I got but after that
+I was planning on using this data to make a graph similar to the example given and from that I could make the program
+realise that point (1,2) and (2,2) are part of the same area. This program does have an error so it doesn't run from what
+I gather because I ran it for the first time just as the competition ended.
