      simplifcation of ONELAB code: · 40ac944c
      Christophe Geuzaine authored
      - removed onelab::region and onelab::function (they complexify the interface, but bring no additional value compared to onelab::string)
      - removed ONELAB2 experiment
      - made client/Model name persistent, and define Gmsh/Model name so that we can uncouple e.g. .geo/.pro pairs
