//help note
//数据对象是JSON格式的树状结构
//对象有俩个成员，m_value 还有 vector<pair<string,数据对象>>
//它俩当中必须有一个是有效的,先检查vector,若空 m_value有效.
//JSON定义中数组的定义不要用，因为无法转换到XML对象.
//XML定义中不要用属性，因为无法转换到JSON对象.
//JSON定义为主，XML支持为辅.
//ini定义只有俩层.
//不要在key定义中使用 【.】 ，因为Boost会把【.】看成是模块的切换点.

//get 用法
//["key"],[idx],[xx].get<double>("key"),[xx].get<double>();
//add 用法:不解释
//update 用法:key,val,idx的形式，没有匹配值的情况用add，有值的情况update
