Detailed Description

Groups the rows of a flat source model into folders by key.

Config::KeysOf_ yields the keys of a source row from its column 0 index, and the row appears under the folder of each of them, a key listed twice counting once. Rows with no keys go into a single unkeyed folder. A folder shows its key as Qt::DisplayRole, the unkeyed one shows Config::UnkeyedLabel_. Leaves expose the columns of their source rows and map back via MapToSource().

A drop onto a folder reaches the source model's dropMimeData() with the folder's key under the Config::DropFormat_ format, empty for the unkeyed folder.

When the keys of the rows change without the source announcing it, ReplaceKey() moves the rows along.

The source must be flat, and its layout changes must move rows as units, as every row sort does. Layout changes of the source are not forwarded, and a source rearranging cells independently of each other is not supported.

A single new key without a folder yet renames the folder of old in place, keeping its rows; otherwise the rows move to the folders of newKeys.
