Detailed Description

NMG topological vertex - the simplest element of the topology system.

A vertex stores knowledge of all the places in the model topology where it is used, via a list of "vertexuse" containers stored in the vu_hd list. Each vertex has its own unique associated geometric point, vg_p;

Neither vertex_g nor vertex structures are the primary topological unit used in describing more complex structures - it is the "use" of a vertex (i.e. the vertexuse structure) that manifests an active vertex point in the model.
