[Gmsh] API define periodic line

[Artur Palha]

Dear Christophe,

I have one more question. After adding the periodic lines how can I have
access to the periodicity information (master/slave) for the nodes of the
mesh? Similar to what is found between $Periodic and $EndPeriodic in the
msh file.

Once again thank you.
