/**
 * YDataSet Class: Recorded data sequence, as returned by sensor.get_recordedData()
 *
 * YDataSet objects make it possible to retrieve a set of recorded measures
 * for a given sensor and a specified time interval. They can be used
 * to load data points with a progress report. When the YDataSet object is
 * instantiated by the sensor.get_recordedData()  function, no data is
 * yet loaded from the module. It is only when the loadMore()
 * method is called over and over than data will be effectively loaded
 * from the dataLogger.
 *
 * A preview of available measures is available using the function
 * get_preview() as soon as loadMore() has been called
 * once. Measures themselves are available using function get_measures()
 * when loaded by subsequent calls to loadMore().
 *
 * This class can only be used on devices that use a relatively recent firmware,
 * as YDataSet objects are not supported by firmwares older than version 13000.
