#%% Simple test for real space computation (using a wavelet based poisson solver),
#%% no forces, just an H atom in an empty box. The cut-off is unrealistic. This
#%% test tests the following part of the code :
#%% * psp spline generation for real space ;
#%% * local part of potential from pseudo ;
#%% * ion-ion interaction computation (instead of Ewald) ;
#%% * Hartree potential with Poisson's solver.
