include embeded entities in boundary list in msh file format
This is a feature request, not a bug report. The $Entities section of .msh file format contains the list of the entities forming the boundary of each entity. It would be handy if the list of embedded entities could be provided also (eg. Line In Surface). The problem I'm facing, is that I'm trying to filter a mesh based on physical tags provided by the user. If I keep all entities with this physical tag and the entities bounding those entities, I miss the embedded entities (and the elements of the parent entity points to non existing nodes). Similarly, the api gmsh.model.get_ajdacencies seems to ignore completely the embedded entities.
