Deletes or nulls out any references to COM objects, DOM nodes, or other disposable objects. Classes that extend {@code goog.Disposable} should override this method. For example:

mypackage.MyClass = function() {
goog.Disposable.call(this);
// Constructor logic specific to MyClass.
...
};
goog.inherits(mypackage.MyClass, goog.Disposable);

mypackage.MyClass.prototype.disposeInternal = function() {
mypackage.MyClass.superClass_.disposeInternal.call(this);
// Dispose logic specific to MyClass.
...
};
