Detailed Description

Implementation of bicubic interpolation.

This class will interpolate in 2D using a bicubic hermite spline.

static XCache& LHAPDF::LogBicubicInterpolator::_getCacheX	(	const KnotArray1F &	subgrid,
		double	x,
		size_t	ix
	)

static

Get and update the current caching structs for interpolation params.

Note: Caches are handled separately for x and Q since they can be sampled very differently.
