 * 作者:    水煮肉片饭(27185709@qq.com)
 * 描述:    数据看板
 * 节点挂上该组件，就可以在游戏运行过程中，直观看到节点任意属性（包括节点脚本中的属性）
 * 可以图形化展示以下四种数据：
 *          轮廓盒子：          随节点旋转，代表节点的实时矩形
 *          碰撞盒子：          不随节点旋转，一般代表碰撞范围
 *          自定义参数：        节点自身属性，以及节点任意脚本中的属性
 *          锚点：             锚点位置会显示一个小红点
 * 自定义参数（配置想监控的数据）：
 *          wp：               世界坐标
 *          radian：           节点弧度（单位：π）
 *          matrix:            变换矩阵
 *          自身属性：          x,y,parent,children等
 *          脚本属性：          脚本实例对象的属性
 * ↓↓参数可以用3种分隔符隔开↓↓
 *          英文逗号、英文冒号、空格
 * ————————————————————————举个栗子————————————————————————
 * 脚本：    Hero
 * 参数：    wp,scale,angle,#angle,#hp
 * 显示结果：世界坐标,节点scale,节点angle，Hero对象的angle,Hero对象的hp
 * ————————————————————————温馨提示————————————————————————
 * 初始化的时候，设置全局变量window['DATABOARD'] = false可屏蔽本项目所有DataBoard，不会产生任何额外开销\n
