 *

 * @param $nid

 *   Project node ID to get committers for.

 * @param $sort

 *   Optional ORDER BY clause to use for the list of committers. Defaults to

 *   sorting by the most recent commit.

 * @param $header_with_order

 *   The value used by TableSort::orderByHeader() in the query or NULL to use

 *   the default.

 * @param $only_maintainers

 *   Optional boolean to indicate if the list should only include users that

 *   currently have VCS write access to the project. Defaults to TRUE.

 * @return

 *   Array containing objects of committer information, keyed by uid.
