I'm using RegionBoundingBox.region inside of `processCues` now. Instead of calling `hasCue()` on RegionBoundingBox we check if `regionBox.region.id === cue.id` directly in `processCues`. Do you have a preference on doing it this way or adding back `RegionBoundingBox.hasCue()` and renaming it to something like `shouldAddCue()` ?
