Implements the Natural Neighbor Interpolation algorithm of Sibson (1980, 1981). This technique interpolates values stored on a Delaunay triangulation. Returned values are continuous everywhere and smooth everywhere except the vertices of the triangulation. Implementation of the algorithm is described in detail in Hipp et al. (1999).

Update the vertices and their associated interpolation coefficients, that will be used to interpolate new values. Uses the natural neighbor interpolation algorithm originally proposed by Sibson, R. (1980), A Vector Identity For Dirichlet Tessellation, Proc. Cambridge Philosophical Society, 87, 151-155. The algorithm is described in detail in Hipp, J. R., C. J. Young, S. G. Moore, E. R.
