[Dune] Bug when construct yaspgrid with non-trivial origin

[Oliver Sander]

Hi Junming,

an object of type YaspGrid<2> always has one corner hard-wired to (0,0).
If you want that corner to be somewhere else you have to use

YaspGrid<2,EquidistantOffsetCoordinates<double,2> >

In other words, change your code to

  Dune::YaspGrid<2,EquidistantOffsetCoordinates<double,2> > grid({-1.0,1.0}, {-1.0,1.0}, {2,2});

Best regards,
Oliver
