/**

 * \brief Takes probed values of different types and outputs the
 * current time plus the value with both converted to doubles.
 *
 * The role of the TimeSeriesAdaptor class is that of an adaptor
 * class, to take raw-valued probe data of different types, and output
 * a tuple of two double values.  The first is a timestamp which may
 * be set to different resolutions (e.g. Seconds, Milliseconds, etc.)
 * in the future, but which presently is hardcoded to Seconds.  The second
 * is the conversion of
 * a non-double value to a double value (possibly with loss of precision).
 *
 * It should be noted that time series adaptors convert
 * Simulation Time objects to double values in its output.
