The class `Triangulation_ds_vertex_base_2` can be used as the base vertex 
for a `Triangulation_data_structure_2`, it is a model of the concept 
`TriangulationDSVertexBase_2`. 

This base class can be used directly or can serve as a base to derive 
other base classes with some additional attributes (a color for 
example) tuned for a specific application. 

Note that if the `Triangulation_data_structure_2` 
is used as a parameter of a 
geometric triangulation, there are additional geometric requirements 
to be fulfilled by the vertex base class, 
and `Triangulation_ds_vertex_base_2` cannot be plugged in.
