hopest_p4est_geom memory problems, need to be debugged
Remove warnings from hopest

We also changed integer types in p4est_cwrapper.
Likely the rest of hopest that calls the interface needs changes.
Started to implement a funtion that maps p4est tree coordinates to high order geometry read by hopest
Merge remote-tracking branch 'malte/master' into highorderp4est
Git commit 4602a771b65251839fb3d7a4fdd581da870cb076 von Carsten (C
Datentypen Definition richtig, warnings raus) teilweise uebernommen (fehlt nocht refine_wrapper etc)
Erste Version der prepare_mesh.f90
We can now build the p4est_geometry function and print curved geometry to .vtk file
Merge with Johannes for HighOrder VTK visualization
Allokieren von SideToElem, ElemToSide etc. Prepare_Mesh läuft jetzt ohne
Fehler durch. Jetzt mal an die Flexi Integration fürs Testen.
Merg mit Thomas und ganz kleine aenderung von Carsten in der example/hopest/Makefile.am
Merge with carsten/debug
hopest compiles without warnings
hopest_p4est_geom can now open an hdf5-file via hopest and get the p4est_connectivity from it
Einige Makefile Anpassungen fuers linken zum Flexi. Fortan Modules werden
bei make install nach local/include kopiert.
added p4est_wrapper.h
Fix two integer return parameters
Clean fortran .mod files
Merge branch 'master' into master_new
