[Gmsh] Face <-> Elements Connectivity Info

[Kostas Politis]

Dear Authors/All,

  Its been almost a week since I have started using Gmsh. Everything works great for me and 
I think I will be using your code for a long time. Here is my question. 

Is there a way of generating automatically(by Gmsh) the topology(connectivity) information
"face to/from element" ? To clarify, the index of left and right element of each face and/or the 
faces' indices for each element. Currently, I am reading the .msh file and I have to check each 
node triplet(say for a triangular face) of each element with every other element's node triplets. 
A part of the output file that would contain every face would also help. 

Thanks for your time !

Sincerely,
Kostas
