一直搞不懂这个定时器怎么用的，正好程序里面有个例子，实验了一下

主要是这个drive(),这个定时器需要自己调用drive驱动

 tf->driveTimer();
 boost::this_thread::interruptible_wait(100);

interruptible_wait表示等待100ms，如果时间是100ms，就没有定时器到时间，1000ms则每次myTimer1总会执行，myTimer2，myTimer2则不一定,2000ms则myTimer1,myTimer2则每次执行，
myTimer3不一定，3000ms则三个定时器都会执行，看这个wait时间的多少。时间少了就没有定时器执行，多了则都会执行。具体程序中用，还需研究。
