The last discussion about the prototype

1：create Object

2：create function

3：create a rule：all instance must have __proto__, and it reference to Father's prototype

4：create a rule：the prototype is object，and it has a attribute named constructor，the constructor reference to it self

5：correct Object，set it`s prototype null，and set it`s __proto__  reference to Function

6：create Date、Array、Math、Function by Function
