Adding the ennemies sprite
Proto enemy and initBox/4 function
Code cleanup

for the addition of collide(BoxLogic, MissileLogic). BoxLogic now knows
about MissileLogic, but MissileLogic doesn't know about BoxLogic
Missile hitting almost working

There is a gap between the hitBox and the sprite
Fixing the collision gap.The hitBox x and y fields are the upper left pixel of the rectangle
Comment modification
updateBoxTowards

Adding a function allowing a BoxLogic to move towards another one.
Splitting updateBoxTowards in two, removing pointer params
Removing pointers. The game runs but is very slow.
Working spawnEnemy function. No box/box collision
Starting to change the enemy tracking system. It will move directly to the players box, through a straight line.
Enemies movement looks just like I wanted it. Good.
TODOS modifications
Decoupling the enemy behaviour from boxLogic
Enemies collision ! Enemies are repelled from one another if they collide
CBP update
