Class
    Foam::cellPointConnectivity
 
Description
    This class provides ordered connectivity for each point of each cell. Lists
    are available of the points and faces surrounding each point of a cell. The
    lists are ordered so that the connected points describe a polygonal cone.
    For a convex cell, any three sequantial cone edges form a positive basis.
