[Insight-developers] AutomaticTopologyMeshSource

[Luis Ibanez]

Hi Mark,

This sounds like a great idea.

I'm not sure if this should be a MeshSource, since there will be
an Update() method but the actual construction of the Mesh is
done through calls to AddTriangle, AddLine... and so on.

Maybe it will be enough to document the class to make clear that
all the invokations to AddTriangle() should be done before calling
Update().
