partition_nei_from_points: Find cpartition neighbourhood from underlying graph
In shazhe/mvst0: Multi-variate ST modelling on globe

Description Usage Arguments Value Author(s)

This function takes a set of points with a field class and the neighbourhood list of those points, and computes the neighbourhood list of the super-graph composed by treating the class as a vertex in its own right. If even one underlying vertex has a nerghbour in another partition, then that partition is the present partition's neighbour.
