Handle a "immobile" state for all actors (no movement, no forces and no deflections)

Sometimes, objects disappear from the screen (velocity and center vector components set as NaN). It happened at high velocities or beyond a certain time. Check for Math.sqrt with negative values or division by zero.

Add a "ghost" state to all actors (no collision)

Finish the box-box collision. Steps to follow :

• calculate the Minkowski difference between the two objects
• test if the shape contains the origin
• if so, compute the MTV (Minimum translational vector) between the Mink shape and origin

Implement rotation, rotation speed and angular momentum for all objects

Add the ability to add a sized zone to the scene where all actors will be subjected to a global oriented force (Vector) in order to simulate gravity

Try to implement a non-immutable vector (to avoid instanciations) and change components type from Number to FloatArray32.

Add two parameters on actors :

• elasticity [0;1] : reduce the amount of normal velocitiy during collision
• friction [0;1] : reduce the amount of tangential velocity during collision

The lowest one is used for computation between two objects
