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.
High order interpolation for refinement, some cleaning.
merge with new module structure
refines combinable, bugfix in BC refinement, arbitrary  number of BC refinements possible.
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
Added shell refinement and supersampling to NGeo instead of corner nodes.
MOD_ReadinTools has to be build before MOD_P4EST: order is changed in the src/Makefile.am (also isoverystring.f90)
code cleaning.
Merge mit Malte/Master
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.
