Controlling classes or methods with Function object properties

You can specify the object that a function is applied to and the parameter values that are passed to the function, using the `call` and `apply` methods of the Function object. Every function in ActionScript is represented by a Function object, so all functions support the `call` and`apply` methods. When you create a custom class using a constructor function, or when you define methods for a custom class using a function, you can invoke the `call` and `apply` methods for the function.
