Detailed Description

Linear interpolation over 4d array including magnitude interpolation.

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

This uses a quad-linear algorithm to interpolate a 3d 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.

This is based on an extension of the trilinear algorithm described in BDSInterpolator3DLinear.hh.

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 BDSInterpolator4D.
