- * This script makes the Sphinx sidebar collapsible.

- * .sphinxsidebar contains .sphinxsidebarwrapper. This script adds
- * in .sphixsidebar, after .sphinxsidebarwrapper, the #sidebarbutton
- * used to collapse and expand the sidebar.
- *
- * When the sidebar is collapsed the .sphinxsidebarwrapper is hidden
- * and the width of the sidebar and the margin-left of the document
- * are decreased. When the sidebar is expanded the opposite happens.
- * This script saves a per-browser/per-session cookie used to
- * remember the position of the sidebar among the pages.
- * Once the browser is closed the cookie is deleted and the position
- * reset to the default (expanded).

Synchronously wait for a file’s status to reach a terminal state.
Returns an exception and the final state if it timeout is exceeded. Uses
exponential backoff to avoid overloading the files server with poll
requests. Returns True on success.
Construct an Agave URI for system ID, path, (filename)
Validation that URI points to a real resource is not implemented.
Should we choose to do this, it will be expensive since it will
involve at least one API call.
AgaveDB is multiuser-aware key/value store built using the Agave metadata web service API.

The library interface is modeled on pickledb, which is inspired by Redis. Eventually, it will support Agave-based permissions and sharing. If you need a more
-document-oriented solution, you can utilize the underlying Agave metadata service.
