[Gmsh] API define periodic line

[Artur Palha]

Christophe,

It works like a charm! Thank you very much for the extremely quick
addition. One thing, I need to add a gmsh.model.geo.synchronize() begore
the periodic line right? Otherwise the entities are not available (just to
be sure I am not missing anything).

Once again thank you!

P.S.: I tried both, and yes the SDK is much easier (at least for quick
tests).
