[Dune] Explanation to box shape functions.

[Patrick Leidenberger]

Hi all,

is it possible to give a little bit more detailed description of the box
shape functions in dune-disc? Or some references?

Is there an error in the documentation:
http://www.dune-project.org/doc/doxygen/dune-disc-html/classDune_1_1P1CubeShapeFunction.html

The equations are not typeset with latex. And what is the meaning of
... {j=0}^{dim-1} ... ?

Thanks a lot

Patrick
