  Calibrator.h
  
  This abstract class provides an interface to various calibration strategies for sensor data.
  A calibration strategy will use an array of pre-collected sensor data to compute optimal model
  parameters. Once this is done, the Calibrator can ransform raw observations from the stream into
  calibrated observations.
