fd/in should provide a default domain if none specified

Question

This domain should probably be (interval 0 Long/MAX_VALUE). In order for this to work this means we should probably accept passing in the vars to assigned domains as a seqable. It would be easy to accept the current way and this new way since if the first arg is not a symbol then the new behavior is being requested.

(fd/in [x y]) (fd/in [x y z] (interval 0 10))
