> As proposed on the devlist, updating concat() to accept traversal varags.
> Also to update `concat()` to not special treat `inject()` in parameters and 
> use `TraversalUtil.apply` on it as with any other child traversals. 
> So the corrected result as inject() behaves by default (The inject() step 
> injects the incoming traverser as the first item in the stream by default) 
> would be:
> {code:java}
> gremlin> g.inject("a").concat(inject("b"))
> ==>aa{code}
