// This method gives you an easier way of calling super
// when you're using Backbone in plain javascript.
// It lets you avoid writing the constructor's name multiple
// times. You still have to specify the name of the method.
//
// So instead of having to write:
//
//   User = Backbone.Model.extend({
//     save: function(attrs) {
//       this.beforeSave(attrs);
