PSYS Template

Important: You might want to use llLinkParticleSystem instead of llParticleSystem dependant upon the desired effects.

--BETLOG Hax SLT: July 9th 2009

All of the flags for making particles in a script with important inter-relationship comments only.
(declaring a bunch of variables instead of just learning to read the actual flag names is stupid)
