* function:气泡提示效果
* use:$("selectors").bubble({fn:getdata, width:width, height:height});
* 对所有需要气泡提示效果的对象使用bubble方法，
* fn为气泡中显示内容获得方法,即fn中返回的数据会显示在气泡中
* 以样式指代div则有:
* width\height为contents的width\height属性
* 气泡总width为left.width + contents.width + right.width
* 气泡总height为top.height + contents.height + bottom.height
