Detailed Description

template<typename ET>
struct vspline::detail::grev_generator< ET >

we need a 'generator functor' to implement grid_eval using the code in wielding.h. this functor precalculates the b-spline evaluation weights corresponding to the coordinates in the grid and stores them in vectorized format, to speed up their use as much as possible.
