Class Hierarchy Analysis Example
public class Main {
public static void main(String[] args) {
H h = new H();
h.m();
// receiver has a declared class H, which is a subclass of C and H does not override method m
// therefore we are sure we are calling C.m here.
A a = new C();
a.m();
// We can be sure we are calling C.m here as A is never instantiated.

This is a fork of jmb's awesome widget that grabs the events with a private address instead of going through the tiresome process of Google's OAuth authentication.
