Functor to do the 3rd order interpolation of node values.

Parameters
[in]sources_and_weightsA pair of two vectors

sources_and_weights.first() is the vector of source entity indices in the source mesh that will contribute to the current target mesh entity.

sources_and_weights.second() is the

Parameters
[in]targetCellIDThe index of the target cell.
[in]sources_and_weightsVector of source mesh entities and corresponding weight vectors. Each element of the weights vector is a moment of the source data over the target entity; for first order interpolation, only the first element (or zero'th moment) of the weights vector (i.e. the volume of intersection) is used. Source entities may be repeated in the list if the intersection of a target entity and a source entity consists of two or more disjoint pieces
Todo:
must remove assumption that field is scalar

implementation of the () operator for 3rd order interpolate on nodes Method: Uses an SVD decomposition to compute a quadratic multinomial fit to a given field, and approximates the field using the quadratic multinomial at points around the central NODE.

Todo:
Should use zip_iterator here but I am not sure I know how to
