An example of an object which requires an implementation of the interface.

				//This code is valid, and the execution will be successful.
				function executeInterface1(executeThis){
					var castedIface = executeThis.cast('TestInterface');
					castedIface.testMethod1(1,2,3);
				}
				//This code is valid, but the execution will not be successful.
				function executeInterface2(executeThis){
					var castedIface = executeThis.cast('TestInterface');
					castedIface.testMethod2(4,5,6);
				}
			

Alright, lets instanciate, the objects and set them to variables. Feel free to type in the variables and take a look, on the firebug window!

				InitedTestObject = new TestObject();
				//variable not used in this example, but I thought I would still make it available!
				CastedTestInterface = InitedTestObject.cast('TestInterface');
			

Ok, so lets try it out! We wrap it all up in some simple div tags with onclick events.

				onclick="executeInterface1(InitedTestObject)"
				onclick="executeInterface2(InitedTestObject)"
			

Yes I know putting it onclick events within div tags lessens the awesomness of the example, but I am not going to hassle the reader with the event model.
