Today We Did
1. Create a file called wall_explosion.py for the WallExplosion class which: a. uses all the images in assets/Bricks to make an animation (have something like tank's get_next_image) b. once you've shown all the images, call self.kill() 2. In main, create the wall_explosion_group. 3. Add a collision between the bullet and the wall. Both should disappear when they collide, but create a new WallExplosion in the place of the wall.
