Seperate out RxJavaAssemblyTracking

[timmutton-agl]

I'd like to include RxJavaAssemblyTracking in a project, but don't need the other stuff. would it be possible for RxJavaExtensions to be its own lib?

No. It would be a maintenance burden. Also why is it a problem, Android? ProGuard should work.
