The BoundaryEntity has to be implementedt still.

Furthermore all classes of SimpleGrid are now derived from the default
interface classes.

Coordinates were seted up wrong. Now it works.

For this reason fro each time the method 'access' of discrete function was
called the method 'done' has to be called to free the local function.

this method. Sometimes we dont nned this method.

Furthermore removed the interface for LocalFunctionInterator because we
dont nned this.

[[Imported from SVN: r194]]

The implementation of the management moved to agmemory.hh.

[[Imported from SVN: r193]]

Access to neighbor was tuned. Now ist a lot fast due to
stack management of NeighborEntity in NeighborIterator.
The Objects are first generated with new and then holded until
the corresponding grid is deleted.

This is a special implementation of the discretefunction interface which

For this grid only ascii format is supported, because
we have to store only H and N.

grid via the interface methods of a grid implementation. This Method works
for all Grids and reads/writes the grid infromation file with type
information ...

[[Imported from SVN: r180]]

The interface is to write one file which contains
information about the grid type and then use the writeGrid
method which is unique for each grid.

Therefore I added two methods in GridDefault, grid2File and file2Grid.
These methods write/read a grid ,i.e. the grid information file and then
they call the writeGrid methods of the actual implementation.
If a grid is written to 'grid' then the grid information is written to file
'grid' and the grids are stored in grid|timestep, i.e. grid0000000000.
For generating these filename I added a routine genFilename ind misc.hh.
