[Gmsh] A suggestion of adding RCM algorithm to GMSH

[Chijie Zhuang]

Dear author of GMSH,
I searched the document, and did not find contents about re-ordering the nodes.

Would you please add interior support for node number re-ordering algorithm, for instance, Cuthill-McKee permutation , such that the band width of the stiff matrix in finite element method would be even less?

Thank you and best regards.
