- Add process_raw() method to the API. This is inteneded to be invoked on any raw output (i.e. not MeasurmentCsv) generated by an Instrument. - Both process() process_raw() are portional to be overriden by impolementation; the default behavior is to return an empty list. - The output specification for both is extened to allow MeasurementCsv's, as well as DerivedMetric's. - Documentation has been reworded for clarity.
