Hi Oli,

the compile option you suggested, i.e.

make -DGridType=AlbertaGrid\<2,2\>

is indeed as nice solution of the grid selecting problem.
However, doing this will still lead to the problem with linking the 
correct library, for example for AlbertaGrid.
Another drawback is, that every grid implementation that should be 
selectable has to be included in order to apply the above solution.
The gridtype.hh can select the grid includes which does reduce 
compilation time.

So you see, no current available solution of this problem is perfect.
