57 // <etymology>
58 // CLIP means CLInterpolator (its base class).
59 // The 2D means that interpolation in 2 dimensions needs to be done.

61 
62 // <synopsis>
63 // CLIPNearest2D is a realisation of the abstract base class CLInterpolator2D.
64 // This class interpolates in a very simple way by taking the nearest
65 // neighbour.
66 //
67 // Note that the base class contains the lattice to be interpolated and
68 // the axis to be used in the interpolation.
