[Gzz] Vertex documentation

[Matti Katila]

Dear Tuomas,

I need some documentation of Vertex(er).

I put days in calendar like this:

    for (int i=1; i <= days; i++) {
        // count column and row
        // i to char buffer

        Vertexer<Coords> v(coords1);

        Text::renderIter(*r, buffer, buffer+strlen(buffer), 
            column , row, v
        );
    }

Just want to know how I can scale the numbers better.
