In units :
QXTank1 is for task2 (only copies a tiny_tank)
DisTank is for task4 (issue #368 )
QHCritTank is for task4 (issue #357 ) (cooperating with 黄文杰)
In bullets :
RangeBall is for task4 (issue #413 )
RandomBall is for task4(issue #357 ) (cooperating with 黄文杰)
对于issue #357 ，齐轩通过随机算法，在bullets中加入了有特定暴击率的RandomBall，并在units中加入了相应的QHCritTank，黄文杰.通过宏定义ADD_SELECTABLE_CRIT_BULLET实现：引用同学们写的各种子弹并且.在打击目标周围生成了10个随机的子弹，速度都指向打击目标。
