* Added a parameter and routine to read in data with timesteps saved in separatediener2004-10-01

For now the filenames has to be in a specific format (for example the filename for iteration 2 for gxx should be gxx_000002.h5 and the filename for iteration 142 should be gxx_000142.h5). This is the format used by the NASA Goddard group. git-svn-id: http://svn.einsteintoolkit.org/cactus/EinsteinAnalysis/EHFinder/trunk@187 2a26948c-0e4f-0410-aee8-f1d3e353619c

If it is only approximately stationary, the evolution of the level set function is dubious but the trial surfaces might get closer to the real event horizon. Testing is definitely necessary. Don't use it unless you really know what you are doing. The implementation is also slightly dubious, since I modify cctk_iteration to start out with negative iteration numbers. There might be a more elegant way of doing this. git-svn-id: http://svn.einsteintoolkit.org/cactus/EinsteinAnalysis/EHFinder/trunk@167 2a26948c-0e4f-0410-aee8-f1d3e353619c

| | | | | | | | | | | | | | integrals over all surfaces. Still only supports full mode. Only weakly tested. There is a problem with the outputs in multiprocessor mode. The results of the integration are stored in 1D grid arrays. However if I use DISTRIB=DEFAULT (taking care only to store results on the correct processor), the output fails if the number of processors are bigger than the number of elements in the grid array (essentially some processors contains a chunk of length zero). If I on the other hand uses DISTRIB=CONSTANT, it works but on multiple processors i get multiple copies of the data in the output. git-svn-id: http://svn.einsteintoolkit.org/cactus/EinsteinAnalysis/EHFinder/trunk@90 2a26948c-0e4f-0410-aee8-f1d3e353619c
