FieldBivariateFunction interface is lacking in BicubicInterpolatingFunction (similar lack on TricubicInterpolatingFunction)

[Krys06]

The BicubicInterpolatingFunction class is missing the implementation of the FieldBivariateFunction interface in order to be able to evaluate the interpolation with "Fielded" inputs.

For the same reason, the interface FieldTrivariateFunction is missing, with its implementation in the TricubicInterpolatingFunction class.

Hello,

I made the evolutions in my project. Here are the files I modified (and created) if it can help.
