PMListScreen table_data return value

This is just for discussion.

On iOS, the return value for `table_data` is an `[]` of sections. Each containing `{cells:[]}` to get to the goods. Make sense.

On Android, we have the same interface, but we don't have sections over here, so I feel like the interface isn't quite right.

Our current implementation says `[]` -> `PMBaseAdapter` and `{adapter: ...}` -> `PMCursorAdapter`.

It'd be super cool if `{cells: []}` could invoke the base adapter too.

I'm creating a lot of `[{cells: cells}]` return values from my `table_data` screens. It'd be nice if it were just `{cells: cells}` or even just `[{cell 1},{cell2}]`.

Just wanted to throw it out there because sections won't be a native thing on Android.

Holy crap this is so not a big deal. I'm cool with a `wontfix` label of shame. Just my $0.02 (Canadian).

Review the PMListScreen table_data contract and the PMBaseAdapter and PMCursorAdapter paths mentioned in the issue; no file or test is identified. Before implementation, establish the desired Android return shape and completion criteria with maintainers.
