Script interface for the Particle System Lights module.
The lights module allows you to attach realtime Lights to a percentage of your particles.
The lights module is a simple and powerful module that allows particles to cast light onto their environment easily. Lights can inherit properties from the particles they are attached to, such as color and size. Point and Spot Lights are supported, including shadow casting and Light cookies.
Particle System modules do not need to be reassigned back to the system; they are interfaces and not independent objects.
