[Dune] dune-geometry r44

[Martin Nolte]

Hi Christoph,

no, that was indeed not intended and is hopefully fixed. All I wanted is to 
use a Dune::array to store the reference elements instead of a C array, so I 
could provide iterators without additional work.

Originally, this Dune::array stored GenericReferenceElement< ... > and, hence, 
its value_type was exactly what we wanted to export. Unfortunately, the 
constructor (and destructor) of GenericReferenceElement is private and, hence, 
the Dune::array had no constructor. To circumvent this, I added a nasty hack: 
The Dune::array now actually stores a derived type with a public constructor / 
desctructor. If anyone knows a better trick, I'd be thankful.

Best,

Martin
