Detailed Description

The files of one picked folder (not its sub folders): turns the rows a documents provider answered into PickedQueue.Entry values.

The query itself (Android) sits behind RowSource, so this logic needs no Android classes. At most MAX_ROWS rows are read, directories are skipped, text of the provider is cleaned.
