[Gmsh] gmsh fails to create points inside a loop

[Eric Nutsch]

Though I havent had time to review your code explicitly, I know one
possible stumble...

Gmsh can not create two points at the exact same point in space(in
addition to not having the same identifier). This is a likely mistake
when using loops, and I find myself running into that problem
frequently.

Hope that helps,
Eric
