Detailed Description

Container to calculate weights for interpolating directly from vertices of cell using Mean Value Coordinates.

Based on (VTK's vtkMeanValueCoordinatesInterpolator's) implementation of "Spherical Barycentric Coordinates" 2006 paper Eurographics Symposium on Geometry Processing by Torsten Langer, Alexander Belyaev and Hans-Peter Seide
