[Catalyst] Catalyst::Action::REST with multipart uploads

[Robert Rothenberg]

I'm wondering if it's possible to use Catalyst::Action::REST with multipart
uploads, so that one can POST or PUT a data structure with an attached file.

The use case would be a RESTful API for uploading attachments. The XML or
JSON data structure would contain metadata about the object, and the
possibly attached file would contain the object being uploaded.

The Catalyst::Action::REST distro includes a
Catalyst::Action::DeserializeMultiPart module, but I am unsure if this would
be used for just desrializing multiple data structures or can be used to
include binary attachments to th data structure.
