[yt-users] support for particles in Orion

Hi All, I'm quite pleased to announce that Orion's StarParticles are now supported by yt, thanks to Andrew Myers. It would be great if any Orion users could test them. You can find this in the unstable repository, at https://bitbucket.org/yt_analysis/yt Thanks, Andrew! j ps--the wiki has been updated to reflect the now full support for orion.
