mass Framework class模块v12

最近为类工厂升级，为它添加了许多时麾的功能，如方法链，extend子类生产器。

例子：

require("class", function($) {
    var Animal = $.factory({
        init: function(name) {
            this.name = name
        },
        getName: function() {
            return this.name;
        },
        setName: function(name) {
            this.name = name;
        }
    });
    var a = new Animal("zzz");
    var Dog = $.factory(Animal, {
        init: function(name, age) {
            this.age = age;
        },
        getAge: function() {
            return this.age;
        },
        setAge: function(age) {
            this.age = age;
        }
    });
    var dog = new Dog("dog", 222);
    console.log(dog);
})
