sub.lh_gray_vertex_to_voxel_nearest_interpolation is a scipy sparse matrix representing the
  interpolation from the vertices into the voxels; the ordering of the voxels that is
  produced by the dot-product of this matrix with the vector of vertex-values is the same
  as the ordering used in sub.lh_gray_indices.
The method used is nearest-neighbors to either the closest pial or white surface vertex.
