scala的动态类实现

scala 2.10开始支持动态类型，做个类方面使用，动态对象的成员也可以动态调用。

val person = DynamicImpl()

person.name = "zs"

person.name.value

val bird = DynamicImpl()

bird.sing = (x:Any)=>{ 0.until(4).foreach( _ => {
        print("hello ")
        Thread.sleep(1000)
        print("hello ")
        Thread.sleep(1000)
        println("how are you?")
        Thread.sleep(1000)
    } ) }

person.bird = bird
person.bird.sing()

通过元组解决参数个数问题

person.do0 = (x:Unit)=>println("no parameter")
person.do3 = (x:(String,Int,Double))=>println(" 1st para is "+x._1+", 2nd para is "+x._2.toString+", 3rd para is "+x._3.toString)
person.do0(())
person.do3(("abc",1,2.0))

（7月23日修改，定义一个类更清晰）
