Mid-March of 2017 Feature: Color Circle Pi Sudoku (in honor of Pi Day, March 14)

This shoudn't be hard to solve, but creating it was a big challenge due to all the constraints I put on the desired end product. I had noticed that there are 32 digits of pi up to the first zero. Powers of 2 are somehow inspirational. 32 is also a nice number of starting tiles for an easy level sudoku puzzle. So this was doable. I decide to try to string them all in a row, then just for fun (and to make it a "circle" in some sense) I colored using hsv and made divisions of 256/32 = 8 for the hue. Hence, it completes one circle in perfectly even divisions of pi/32 (or 12.5 degrees).
