[Gmsh] API define periodic line

[Artur Palha]

Dear Benedikt,

Thank you for your reply. Unfortunately I am unable to understand exactly
what you mean by that. Roughly I think that you define the periodic surface
2 (for example) to be the translation along [400,0,0] of the surface 1.
Still you make use of the Periodic Surface call. My problem is that I am
unable to find an equivalent function to Periodic Surface in the API of
gmsh.

To make it clearer: What is the equivalent code using the API of gmsh that
implements:

Periodic Line{mySlaveLine} = {myMasterLine};

Once again thank you for your help.
