[MOAB-dev] Setting connectivity for single vertex

[Tim Tautges]

[cc'ng moab-dev list, since I've left Argonne.]

dummy is 0, which is an invalid handle, but should be the handle(s) of the entities whose connectivity you're setting; I 
suspect what you want there is *vertices.begin().  And you can't set connectivity until you make an element, so you need 
to call create_element, probably with the number of verts per element as 1 and the connectivity just the single vertex 
defining the point element.
