- Feature #813: Space unit has been added for meshes and coords. - Feature #818: FSI is finally done; dev code has therefore been cleant-up. A legacy folder has been introduced in ModelInstances for Models that are not completely reliable (the FSI with one mesh has been put there). - Bug #808: In ALE operator, two indexes were inverted. - Bug #801: In header guards, some path were related to a specific user.
