	 *
	 *
	 * 	The return is a Promise, so multiple .then() can be chained in the usual ways:
	 * 	@example
	 * 	egw.request(...)
	 * 		.then(function(data) {
	 * 		  if(debug) console.log("Requested data", data);

	 * 			{

	/**
	 * The dataFetch function provides an abstraction layer for the
	 * corresponding "EGroupware\Api\Etemplate\Widget\Nextmatch::ajax_get_rows" function.
	 * The server returns the following structure:
	 * 	{
	 * 		order: [uid, ...],
	 * 		data:
	 * 			{
	 * 				uid0: data,
	 * 				...
	 * 				uidN: data
	 * 			},
	 * 		total: <TOTAL COUNT>,
	 * 		lastModification: <LAST MODIFICATION TIMESTAMP>,
	 * 		readonlys: <READONLYS>
	 * 	}
	 * 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
	 * given range.
	 * The dataFetch function stores new data for the uid's inside the
	 * local data storage, the grid views are then capable of querying 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
	 *  currently has no data for the given filter settings.

	 * the fresh data.

	 * @param {function} callback_function A function that will analize the provided fetch
	 *	parameters and return a reproducable cache key, or false to not cache
