Total Points: 20

Note: "Correctly draws" includes any rotation or translation of the image 
  produced by the instructor's solution code on the class website. 
  A "Correctly draws" image may be with each unit length = 10 or any other scale that
  better fills the screen than the default length of 10.
  Lines drawn in different colors in the instructor's solution must be different colors
  in your solution. Lines the same color in the instructor's solution must be the same 
  color in your solution. What those colors are is not specified.

[+2] Deals with bad input as specified.
[+3] Correctly sets custom colors.
[+3] Correctly draws Koch's Snowflake:
       axiom: f++f++f
       rules: f=Gf-Rf++f-Gf; R=; G=
       turn Angle: 60.0;
       generation: 3;

[+3] Correctly draws the Sierpinski Triangle:
       axiom: Bf
       rules: f = h - f - h; h = f + h + f
       turn Angle = 60.0
       generation = 5


[+3] Correctly draws the Peano Curve:
       axiom: f
       rules: Gf+Bh++h-Gf--ff-Bh+; h = -Gf+Bhh++h+Gf--f-Bh; G =; B =
       turn Angle = 60.0
       generation = 3
