- * This file/module/whatever is an attempt to gather all data collection in
- * one place.
- *
- * The basic idea is to have all periodic data updates unified here, with
- * stats, tracking of "ajax overflows" and general-purpose error handling
- * and callbacks and whatnot, instead of all the custom stuff that we
- * started out with.
- *
- * Sources are identified by a name, which is then available in
- * nmsData[name] in full. A copy of the previous data set is kept in
- * nmsData.old[name]. You can use getNow / setNow() to append a 'now='
- * string.
- *
- * nmsData[name] - actual data
- * nmsData.old[name] - previous copy of data
- * nmsData.registerSource() - add a source, will be polled periodicall
- * nmsData.addHandler()
- * nmsData.updateSource() - issue a one-off update, outside of whatever
- * 			    periodic polling might take place
- * nmsData.invalidate() - Invalidate browser-cache.
