写的一个ONE下模拟公交站点的移动模型
主要是为了模拟公交车站站点。
设置实例
#stop Group
Group10.groupID = Stop
Group10.movementModel = MultiStop 移动模型名
Group10.waitTime = 10, 30
Group10.nrofHosts = 59 站点数量
Group10.stopfile= data/city/stop.wkt 站点位置文件
站点文件可以用openjump把线文件（如demo_bus.wkt）转化成点文件。
java代码。
主要是在stationmovement的基础上修改来的。
stationmovement也能设置站点，但是一次只能一个，而且要自己设置坐标。
