 * Update function is basically a hack.
 *
 * We want to remove it but must resolve issues in
 * http://issues.civicrm.org/jira/browse/CRM-12144
 *
 * It is not recommended & if update doesn't work & fix does then update will not be fixed
 *
 * To do this, perform a 'get' action to load the existing values, then merge in the updates
 * and call 'create' to save the revised entity.
 *
 * @deprecated
 *
 * @param array $apiRequest
 *   Array with keys:
 *   - entity: string
 *   - action: string
 *   - version: string
 *   - function: callback (mixed)
 *   - params: array, varies
 *
 * @return array|int|mixed
