 /**
  * Creates a map entry to map between server and client IDs.
  *
  * If an entry already exists, it is overwritten.
  *
  * @param string $databaseURI  URI of database to sync. Like calendar,
  *                             tasks, contacts or notes. May include
  *                             optional parameters:
  *                             tasks?options=ignorecompleted.
  * @param string $cuid         Client ID of the entry.
  * @param string $suid         Server ID of the entry.
  * @param integer $timestamp   Optional timestamp. This can be used to
  *                             'tag' changes made in the backend during the
  *                             sync process. This allows to identify these,
  *                             and ensure that these changes are not
  *                             replicated back to the client (and thus
  *                             duplicated). See key concept "Changes and
  *                             timestamps".
