Particle Manager ideas and api

Hey, I decided to post it to the module topic here, it's still early stages, but just in the hopes someone picks it up and play with it to get some feedback on it.

Also if someone reads the doc and has questions or can't understand something, please ask clarifications. I have some drawings I plan to at some point redo on the computer that I hope can help explaining the system in place a bit.
