/**
* UploadStash is intended to accomplish a few things:
- * - enable applications to temporarily stash files without publishing them to the wiki.
- * - Several parts of MediaWiki do this in similar ways: UploadBase, UploadWizard, and FirefoggChunkedExtension
- * And there are several that reimplement stashing from scratch, in idiosyncratic ways. The idea is to unify them all here.
- * Mostly all of them are the same except for storing some custom fields, which we subsume into the data array.
- * - enable applications to find said files later, as long as the db table or temp files haven't been purged.
- * - enable the uploading user (and *ONLY* the uploading user) to access said files, and thumbnails of said files, via a URL.
- * We accomplish this using a database table, with ownership checking as you might expect. See SpecialUploadStash, which
- * implements a web interface to some files stored this way.

- * UploadStash right now is *mostly* intended to show you one user's slice of the entire stash. The user parameter is only optional
