[Dune] [#655] Alberta GridFactory leaks memory

[Oliver Sander]

Hi Martin, hi all!
I have seen on the commit mails that you guys have recently added 
support for
parametrized boundaries in AlbertaGrid.  Your code does not use any of 
the infrastructure
for this already present in Dune (namely, the BoundarySegment class and the
corresponding method insertBoundarySegment() in the GridFactory).  Could you
explain a bit what you did and why you couldn't use the existing 
infrastructure?
Thank you!

Incidentally, in the documentation of 
GridFactory::insertBoundarySegment() it says
"The grid object takes control of this object and deallocates it when 
destructing itself. "
Maybe we should hand over an std::auto_ptr instead of a plain pointer to 
make this
even clearer.

Yours,
Oliver
