 * A Site entity.

 * \ElggSite represents a single site entity.
 *
 * An \ElggSite object is an \ElggEntity child class with the subtype

 *  - name
 *  - description
 *  - url
 *
 * Every \ElggEntity belongs to a site.
 *
 * @note Internal: \ElggSite represents a single row from the sites_entity
 * table, as well as the corresponding \ElggEntity row from the entities table.
 *
 * @warning Multiple site support isn't fully developed.
