一个简单的分层时间轮实现：类似于3维数组实现时钟

	%%%-------------------------------------------------------------------
	%%% @author zhongwencool@gmail.com
	%%% @doc 一个简单的分层时间轮实现：类似于3维数组实现时钟
	%%% 根据 http://www.embeddedlinux.org.cn/RTConforEmbSys/5107final/LiB0071.html 实现
	%%% 1.时钟原理说明：
	%%% 1.1. 初始化一个三层时间轮:秒刻盘：0~59个SecList, 分刻盘：0~59个MinList, 时刻盘：0~12个HourList;
	%%% 1.2. SecTick由外界推动,每跳一轮(60格),SecTick复位至0,同时MinTick跳1格;
	%%% 1.3. 同理MinTick每跳一轮(60格),MinTick复位至0,同时HourTick跳1格;
	%%% 1.4. 最高层：HourTick跳一轮(12格）,HourTick复位至0，一个时间轮完整周期完成.
	%%% 2.事件原理说明：
