public class BezEllipse
- extends BezShape
Provides factory methods to construct a closed elliptical BezShape.
In methods that do not include a reference to a PApplet in the signature,
the PApplet used for calls to the Processing environment is obtained from
IgnoCodeLib, which must be correctly initialized in setup.
If IgnoCodeLib does not have a reference to a PApplet, it throws a NullPointerException.

/**
* March 14, 2012 3:35:47 PM CDT
* Sample code for IgnoCodeLib Processing library by Paul Hertz
* for IgnoCodeLib version 0.3.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.
* Changes for IgnoCodeLib 0.3 include new package namespaces (net.paulhertz replaces com.ignotus),
* and an IgnoCodeLib class that should be initialized on setup. When IgnoCodeLib is correctly initialized
* as in "igno = new IgnoCodeLib(this);", you no longer need to pass a reference to the host PApplet
* to component constructors in IgnoCodeLib.
