anchor.diff:  An RDFValueCollection is a collection of objects, often URNs or StatEntry
   objects which reference files that have been downloaded. These are often created
   as the output of hunts and it is common to want to download all these files to
  -disk so you can work with them easily.
  -
  -You need to pass in a URN, and by default we will download files from the
  -collection to the directory you specify under the full aff4 path.
  -
  -For collections we support downloading multithreaded, which speeds things up
  -significantly.
  -In addition, for collections, by default dump a yaml file of the client data to
  +disk so you can work with them easily.

  +You need to pass in a URN, and we will download files from the collection to the
  +directory you specify under the full aff4 path.
  +
  +In addition, for collections, you can requests a dump a yaml file of the client data to
   the root of the client directory, e.g. C.123456890abcdef/client_info.yaml.
   This is useful for identifying which machine the files came from when working on
   the filesystem.
