Particle module

Originally starting out as an informal conversation between developers, the particle system capability has grown to be widely used for effects such as rain, snow, fire, smoke among many others. The capability allows for the aforementioned effects to be added to any object that can be created in Wonderland. While at first it was created with the simple ambition to see if it could be done, once we saw what we had accomplished we decided to share module with the Open Wonderland (then Project Wonderland) community at large. Currently a second version is in development to include easier usage, added features, bug fixes, and advanced effects. The particle system capability was created by and is currently maintained by Ryan Babiuch, a developer on the iSocial project, known as "jagwire" within the Open Wonderland community.
