[Gmsh] Change coordinate of a vertex in a GModel using API

[Mikhail Artemyev]

Hi Marco,

I would suggest to remove a wrong vertex from a model using:

void remove(GVertex *v); // from GModel class

and then to add a new (corrected) one:

void add(GVertex *v) { vertices.insert(v); } // from GModel class

However I didn't try that for myself.

Best regards,
Mikhail
