* Sample code for IgnoCodeLib Processing library by Paul Hertz
* for IgnoCodeLib version 0.2.x and above
* In this example, we use the various new methods in IgnoCodeLib 0.2 for creating ellipses and circles.
* These methods belong to the new classes BezEllipse and BezCircle. You can't create an instance
* of these classes with the new keyword because their constructors are protected. Instead, you call
* one of their many "static factory methods" that return an instance of the class. See the code
* below in createEllipses() and createCircles() for examples of each factory method.
