 * 创建对象的可观察代理

 * obj = observable({a:1,b:2,C:{c1:1,c2:2},d:[1,2,3]},{
 *      onRead:(key)=>{console.log('read',key)},
 *      onWrite:(key,value)=>{

 *
 * 当读取obj.a时，会触发onRead(['a'])
 * 当读取obj.C.c1时，会触发onRead(['C','c1'])
 * 当写入obj.a时，会触发onWrite(['a'],value)
 * 当写入obj.C.c1时，会触发onWrite(['C','c1'],value)
 *
 * onRead和onWrite的返回值会作为读取或写入的结果
 * 支持嵌套对象和数组
