[Dune] longest edge alberta

[Martin Nolte]

Choosing the longest edge as refinement edge might result in a segfault in 3d. 
As the unrotated grid might work for Alberta, the DGF parser will not select 
the longest edge by default. You have to tell it by using the grid parameter 
"REFINEMENTEDGE LONGEST".

Best,

Martin
