MV* framework you could understand in a moment

抽象模型：

• 1.基类扩展

    understand.extend({
        fun1:function(){
            console.log('基类扩展)
        }
    });
    var Module = U.class();
    var i = new Module();
    i.fun1();

• 2.创建模型

    U.extend({
        fun1:function(){
            console.log('func1 from base class');
        }
    })
    var Parent = U.class(function(name){
        console.log(name + ' born');
    });
    Parent.augment({
        fun2:function(){
            console.log('fun2 from method prototype');
        }
    });
    var Child = Parent.class(function(name){
        console.log(name + ' born');
        this.fun2();
    });
    Child.augment({
        fun3:function(){
            this.fun1();
           // this.fun2();
        }
    });
    var p = new Parent('parent');
    p.fun1();
    //p.fun2();
    var c = new Child('child');
    c.fun3();

• 3.子类继承
• 4.静态属性、方法

数据绑定：

   var Module = U.class();

0. get

   Module.get(key);

0. set

   Module.get(key, value);

0. filter

   Module.filter(fn);

0. delete

   Module.delete([key | fn]);

0. all

   Module.all(); // return attributes

0. size

   Module.size(); // return attributes size

0. has

   Module.has(key);//return boolean

0. update

   Module.update([key,]fn);

消息分发：

0. on
1. emit
2. detach

通用工具类：

0. each
1. extend
2. clone
3. trim
4. typeof
