Helper function to check how well a set of smooth renewable curve parameters matches the supply-points from which the curve parameters are generated. In gcamdata, this function is used in combination with stats::optimize to minimize the error of the smooth renewable curve fit relative to the supply-points. Note that the first argument (curve.exponent) is the one that is changed by optimize when trying to minimize the error. The functional form of GCAM's smooth renewable resource curve is documented at: http://jgcri.github.io/gcam-doc/energy.html#renewable-resources
