`LoopsStep` should now implement `hashCode()`.
> Support nested-repeat() structures

> Key: TINKERPOP-967
> URL: https://issues.apache.org/jira/browse/TINKERPOP-967
> Project: TinkerPop
> Issue Type: Improvement
> Components: process
> Affects Versions: 3.1.0-incubating
> Reporter: Marko A. Rodriguez
> Assignee: Marko A. Rodriguez
> Priority: Major
>
> All the internal plumbing is staged for this to happen, we just haven't gone
> all the way. In short, a {{NESTED_LOOP}} traverser has an internal
> {{loopStack}} where {{repeat(repeat())}} will have a {{loopStack}} of two.
> The {{it.loops()}} checks of the internal repeat will always check the top of
> the stack and when its done repeating will delete its counter off the top of
> the stack.
> [~dkuppitz]'s work on {{LoopStep}} will be backwards compatible. In
> {{RepeatStep}} we will support:
> {code}
> repeat('a',out('knows').repeat('b',out('parent')))
> {code}
> and thus, things like {{loops('a')}} as well as {{times('a',2)}}. Note that
> naming the loop stack will be a super rare case as most people will just
> assume standard nested looping semantics with a push/pop stack.
