Detailed Description

Cubic interpolation over 2d array.

Does not own array - so multiple interpolators could be used on same data.

This uses a bicubic algorithm to interpolate a 2d array and return the value at any arbitrary point. If the point lies outside the array the default value for the templated parameter is returned (typically 0). Therefore, the field drops to 0 outside the specified region.

Each derived class should implement this function. Note T suffix (was templated) to distinguish it from GetInterpolatedValue which returns Geant4 types and is the main interface to should have the clean name.

Implements BDSInterpolator2D.
