hdf5v -PetscViewer for HDF5 input/output to use with the specified file

-viewer_hdf5_base_dimension2 -turns on (true) or off (false) using a dimension of 2 in the HDF5 file even if the bs/dof of the vector is 1

-viewer_hdf5_sp_output -forces (if true) the viewer to write data in single precision independent on the precision of PetscReal

This PetscViewer should be destroyed with PetscViewerDestroy().
