FS#773 - mesh readers and grid factory
User who did this - Martin Nolte (nolte)
The DGF parser cannot return the factory, because it shall also work with grids that don't provide one (e.g., YaspGrid).
For other grid format readers (AmiraMeshReader / GmshReader) Carsten's suggestion seems reasonable to me. The code could then look somewhat like this one:
GmshReader reader( factory );
reader.read( file );
Grid *grid = factory.createGrid();
Apart from the access to insertion indices, the user can also change the constructor of the grid factory this way. The disadvantage is that a user could read two different grid files into one grid, which might yield unpredictable results.
