Just want to say I *hate* the whole "concerning" thing adding in Rails, which this apes.  I'm doing this only because it makes it somewhat more clear how the various methods I created are grouped.

If there is enthusiasm for the concept of the `DataStore` class, or one like it, I would probably want to actually separate these various methods into different classes, and bring them together here, if needed, thus getting rid of the `concerning` method entirely.  I didn't want to go down that road if this PR was *not* destined for acceptance.
