Request: Publish Tracker on NPM

@timbrandin’s one here looks like the most current. I’ll try to give some feedback on it soon - I can envision using it to build an NPM package that can be used inside Meteor, by declaring Tracker as a peerDependency.

I think it should be tested in both client and server capacities, but since it’s not a library intend to span client and server it need not be built as an atmosphere library and bound to the Meteor package repo, when npm is clearly the larger ecosystem.

Aren’t there separate drivers that add co-routines that enable tracker? Does it really work with these npm packages?
