[dune-fem] Neuman boundary conditions

[Tobias Malkmus]

Hi Justus

As we use the dune grid interface classes in our implementations the
domain can be changed by simply providing another dgf file.

This is done as follows:
In the parameter file, eg. examples-solvers/data/parameter, change the
parameter:
fem.io.macroGridFile_*d
to the dgf file modeling your domain.

As a starting point for dgf files have a look into one of the shipped
files, eg. example-solvers/data/unitcube-2d.dgf

A deatiled description of the dgf Format can be found on the dune
documentation page:
http://www.dune-project.org/doc/doxygen/dune-grid-html/group___dune_grid_format_parser.html
