Filters extra CURIEs available on REST API responses.

CURIEs allow a shortened version of URI relations. This allows a more
usable form for custom relations than using the full URI. These work
similarly to how XML namespaces work.

Registered CURIES need to specify a name and URI template. This will
automatically transform URI relations into their shortened version.
The shortened relation follows the format {name}:{rel}. {rel} in
the URI template will be replaced with the {rel} part of the
shortened relation.

For example, a CURIE with name example and URI template
http://w.org/{rel} would transform a http://w.org/term relation
into example:term.

Well-behaved clients should expand and normalize these back to their
full URI relation, however some naive clients may not resolve these
correctly, so adding new CURIEs may break backward compatibility.
