Vertex

Vertex::

vertex(graph, vertex_function, id, glbl = NULL)

A vertex function

>>> def v_fun(vertex_id, graph, result_vertex, result_edge, vertex_glbl, vertex_edge_vars):
        #Do something
        #Modify result_vertex, result_edge, vertex_glbl, vertex_edge_vars
        #sumbit a request to the graph
        return result_vertex, result_edge, vertex_glbl, vertex_edge_vars

Create vertex (the id must be unique)

>>> v = vertex(g, v_fun, id, var)
