[penlin]
0. implement easy bomb explode
1. apply Item Effect  (power, speed, number)
2. speed control !!!!
vector [speed*{(1,0), (-1,0), (0,1) , (0,-1), (0,0)} ] is the movement that this agent would move in this frame, that is , in next frame, this agent would start at the position after plus that vector

I adjust the game.py/Configuration  position data precision to '0.3f' ,
and I adjsut the function generateSuccesor(self, vector) to detect whether this agent is reach the next dot
