A simple (but flexible enough for most uses) particle system is provided. Particle systems are used to simulate complex physical effects tsuch as sparks, fire, magic particles, smoke, mist, magic, etc.
The idea is that a "particle" is emitted every a fixed interval and with a fixed lifetime. During his lifetime, every particle will have the same base behavior. What makes every particle different and provides a more organic look is the "randomness" associated to each parameter. In essence, creating a particle system means setting base physics parameters and then adding randomness to them.

#### Linear Velocity
Linear Velocity is the speed at which particles will be emitted (in pixels/sec). Speed might later be modified by gravity or other acceleations (as described further below).
