Issue with "SmoothingBicubicSplineInterpolator"
-----------------------------------------------

                 Key: MATH-365
                 URL: https://issues.apache.org/jira/browse/MATH-365
             Project: Commons Math
          Issue Type: Bug
    Affects Versions: 2.1
            Reporter: Gilles
            Priority: Minor


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?
