    * Introduction 介绍
    * ============================================================================
    * 
    * This plugin provide extra event.
    * 这个插件提供额外的事件。
    * 
    * put in event note:
    * 把这东西放进事件的note中来将这个事件导出
    *  <SF_EXTRA_EVENT: eventExtId>
    * 
    * 
    * ============================================================================
    * Plugin Commands 插件命令
    * ============================================================================
    * 
    * SF_Extra_Event Insert_Event <mapId> <evenExttId> 
    *   Add an event to the map.
    *   将一个额外事件添加到地图中
    * 
    * SF_Extra_Event Remove_Event <mapId> <eventExtId>
    *   Remove an event from the map.
    *   将一个额外事件从地图中移除
    * 
    * SF_Extra_Event Ext Show_Balloon_Icon <eventExtId> <ballonId> <waitForComplete>
    *   用来将不在地图上的事件能添加 显示气球图标 的命令
    *   这个命令会在导出事件的时候将其转换成对应的事件指令
    *   eventExtId 事件的额外ID
    *   ballonId 要显示的气球的ID （从1开始计数）
    *   waifForComplete 是否要等待完成，使用 true 或 false，其余样式会作为false来生成
    * 
    * SF_Extra_Event Ext Set_Event_Location <eventExtId> <direct|variables|exchange> <param1> <param2> <direction>
    *   用来设置额外事件的位置 
    *   eventExtId 是设置额外事件的对象 
    *   设置的位置有三种方式 direct variables exchange
    *   direct是直接指定目标位置，param1和param2就是目标的x,y坐标
    *   variables是用变量来计算目标的位置 param1和param2就是目标x,y坐标所在的变量标号
    *   exchange是与地图上的事件进行对换 
    *       param1为normal或ext代表与普通事件或额外事件对换
    *       param2则指定事件的Id，使用0则代指自身
    *   direction则是指定事件的朝向 使用stay, down, left, right, up来代指朝向。
    * 
    * 在设置移动路线时，填入脚本$gameMapsExt.set_route_target(eventExtId)来修改本次移动路线
    * 设置的事件对象，只有最后一次有效。这个脚本是无法执行的，要经过导出转成语义可用的。
    * 
    * ============================================================================
    * Script Calls
    * ============================================================================
