ComboCurve: ARIES Export - Force Forecast/History Match

Force Forecast/History Match is an option available when using Export Scenario to ARIES
                                    
  1. Force Forecast/History Match allows the exporter to "back-forecast" the curve to find what the curve's rate would be at the beginning of the month and exports that as the start rate in ARIES
    1. This eliminates the gap between historical data and the forecast by compromising and allowing initial production rate (Qbeg in ARIES Multigraph) to change
    2. This feature is best used, and is only recommended, when the fit of the curve vs historical data is more important than having the precise initial production rate (Qbeg in Multigraph) honored:
      1. Such as when the ARIES Effective Date is later than the START date of the forecast.
    3. ComboCurve will only perform this transform on forecasts with start dates prior to the As Of Date (Effective Date in ARIES).  Because this transform does a back-calculation of Qi, particularly in the case of steep Arps (hyperbolic) forecasts, even a small backwards extrapolation from the Qi/Qbeg to the beginning of a month can result in significantly higher start rates. 
    4. It is not recommended to move your Effective Date backwards in ARIES after exporting with Force Forecast/History Match because it may cause incorrect rates to be used in your economic analysis.
