Description
There seems to be some kind of expression parser in the dgf parser that allows to generate functions from strings.
Since this functionality is in no way restricted to boundary projections it should be seperated from the dgf-parser and use the dune-common (virtual) function base class.
This would allow to use it also for the standard boundary segments, other grid formats, initial values, ...
A simple ExpressionFunction that can be constructed from a string would be nice.
