facility for writing and reading grids
The BackupRestoreFacility allows writing hierarchic grids to disk and reading them back into another program.
It is guaranteed that all index sets and id sets are preserved by the backup / restore process. The result of restore is undefined, if the number of processes in a parallel program differs from the number of processes used on backup.
There are two pairs of backup / restore methods:
These techniques may not be mixed, i.e., you cannot write the grid into files and read it back from a stream or vice versa. While operating on a std::stream might be convenient, a grid written in another language than C++ might need to emulate this method by writing through a temporary file.
