/*
* MAP对象,实现MAP功能
*
* 接口:
* size() 获取MAP元素个数
* isEmpty() 判断MAP是否为空
* clear() 删除MAP所有元素
* put(key, value) 向MAP中增加元素(key, value)
* remove(key) 删除指定KEY的元素,成功返回True,失败返回False
* get(key) 获取指定KEY的元素值VALUE,失败返回NULL
* element(index) 获取指定索引的元素(使用element.key,element.value获取KEY和VALUE),失败返回NULL
* containsKey(key) 判断MAP中是否含有指定KEY的元素
* containsValue(value) 判断MAP中是否含有指定VALUE的元素
* values() 获取MAP中所有VALUE的数组(ARRAY)
* keys() 获取MAP中所有KEY的数组(ARRAY)
*
* 例子:
* var map = new Map();
*
* map.put("key", "value");
* var val = map.get("key")
* ……
