> I figured out that the name of this class is misleading as the implementation doesn't
perform the intended smoothing.
> In order to solve this issue, I propose to:
> # deprecate the "SmoothingBicubicSplineInterpolator" class
> # create a "BicubicSplineInterpolator" class (similar to the above class but with the
useless code removed)
> # remove the "SmoothingBicubicSplineInterpolatorTest" class
> # add a "BicubicSplineInterpolatorTest" with essentially the same contents as the above
one
> Then I would also add a new "SmoothingPolynomialBicubicSplineInterpolator" where I used
the "PolynomialFitter" class to smooth the input data along both dimensions before the interpolating
function is computed.
> Does someone object to these changes?
