ProfilingAware (Apache TinkerPop 3.6.2 API)

All Known Implementing Classes:

GroupSideEffectStep, GroupStep
```
public interface ProfilingAware
```
Marks a Step as one that is aware of profiling. A good example of where this is important is with GroupStep which needs to track and hold a Barrier, which is important for the ProfileStrategy to know about. Once the ProfileStep is injected the Barrier needs to be recalculated so that the timer can be properly started on the associated ProfileStep. Without that indirect start of the timer, the operation related to the Barrier will not be properly accounted for and when metrics are normalized it is possible to end up with a negative timing.
