Dragon curves. Compose a python program (use sttdraw) to write the instructions for drawing the dragon curves of order 0 through 7. The instructions are strings of F, L, and R characters, where F means draw line while moving 1 unit forward, L means turn left, and R means turn right. A dragon curve of order n is formed when you fold a strip of paper in half n times, then unfold it to right angles. The key to solving this problem is to note that a curve of order n is a curve of order n1 followed by an L followed by a curve of order n1 traversed in reverse order, and then to figure out a similar description for the reverse curve.
