`string` can be ambiguous as `Tuple` layer supports both `byte string`
and unicode `string`.

Because different bindings may issue different limit for get_range calls, it is
impossible to return the same size value for getApproximateSize API. So we just
push a string to make sure binding test results are the same. Use another unit
test to make sure the sizes got back are monotonically increasing.
* The initial plaintext file converts nicely - this just converts operations to small headers and uses < and > to make sure text in <> shows up
* Use inline code in a few places where it makes sense
