* lastModification: <LAST MODIFICATION TIMESTAMP>,

* If a uid got deleted on the server above data is null.
* If a uid is omitted from data, is has not changed since lastModification.
*
* If order/data is null, this means that nothing has changed for the

* The dataFetch function stores new data for the uid's inside the

* data for those uids from the local storage using the
* "dataRegisterUID" function.
*
* @param _execId is the execution context of the etemplate instance
* you're querying the data for.
* @param _queriedRange is an object of the following form:
* {
* start: <START INDEX>,
* num_rows: <COUNT OF ENTRIES>
* }
* The range always corresponds to the given filter settings.
* @param _filters contains the filter settings. The filter settings are
* those which are crucial for the mapping between index and uid.
* @param _widgetId id with full namespace of widget
* @param _callback is the function that should get called, once the data
* is available. The data passed to the callback function has the
* following form:
* {
* order: [uid, ...],
* total: <TOTAL COUNT>,
* lastModification: <LAST MODIFICATION TIMESTAMP>,
* readonlys: <READONLYS>
* }
* Please note that the "uids" comming from the server and the ones
* being parsed to the callback function differ. While the uids
* which are returned from the server are only unique inside the
* application, the uids which are used on the client are "globally"
* unique.
* @param _context is the context in which the callback function will get
* called.
* @param _knownUids is an array of uids already known to the client.
* This parameter may be null in order to indicate that the client

* Search for exact UID string or regular expression and call registered (nextmatch-)widgets refresh function with given _type
*
* This method is preferable over dataRefreshUID for app code, as it takes care of things like counters too.
*
* It does not do anything for _type="add"!
*
* @param {string|RegExp) _uid is the uid which should be refreshed.
* @param {string} _type "delete", "edit", "update", not useful for "add"!
* @return {array} (nextmatch-)wigets refreshed
