      /** This class corrects observables from effects such as antenna
       * excentricity, difference in phase centers, offsets due to 
       * tidal effects, etc.
       *
       * This class is meant to be used with the GNSS data structures objects
       * found in "DataStructures" class.
       *
       * A typical way to use this class follows:
       *
       * @code
       *   // Create the input obs file stream
       *   RinexObsStream rin("ebre0300.02o");
       *
       *   // Loads precise ephemeris object with file data
       *   SP3EphemerisStore SP3EphList;
       *   SP3EphList.loadFile("igs11513.sp3");
       *
       *   // Sets nominal position of receiver
       *   Position nominalPos(4833520.3800, 41536.8300, 4147461.2800);
       *
       *   // Vector from antenna ARP to L1 phase center [UEN] (Leica AT504)
       *   Triple offsetL1(0.1093, -0.0003, 0.0003);   // Units in meters
       *
       *   // Vector from antenna ARP to L2 phase center [UEN] (Leica AT504)
       *   Triple offsetL2(0.1282, 0.0011, 0.0011);    // Units in meters
       *
       *   // Vector from monument to antenna ARP [UEN] for this station
       *   Triple offsetARP(2.510, 0.300, 1.045);    // Units in meters
       *
       *   // Vector due to tidal effects (previously computed)
       *   Triple tides(0.121, 0.033, -0.016);    // Units in meters
       *
       *
       *   gnssRinex gRin;
       *   CorrectObservables corr(SP3EphList,
       *                           nominalPos, 
       *                           offsetL1,
       *                           offsetL2,
       *                           offsetARP,
       *                           tides);
       *
       *   while(rin >> gRin) {
       *      gRin >> corr;
       *   }
       * @endcode
       *
       * The "CorrectObservables" object will visit every satellite in the 
       * GNSS data structure that is "gRin" and will correct the 
       * corresponding observables from the given effects.
       *
       * When used with the ">>" operator, this class returns the same 
       * incoming data structure with the observables corrected. Be warned
       * that if a given satellite does not have the observations required, 
       * it will be summarily deleted from the data structure.
