// We need to be able to :
//		- Allow lights to exist outside the context of a LightController
//			- i.e we can have a prototype light or similar
//		- Preserve the existence of lights upon object destruction
//			- No need to keep track of an object only used upon special use cases
//		- Maintain an X*N byte array, X = size of packed data, N = Light number
//			- But still allow classes of size Y bytes
//			- Preserve X packed bytes in an array which are pointed to by an array of shared pointers
