0a3d1036e2 BOUNDARIES: improve the divergence free boundary conditions. 
- in order to find the boundary value for normal magnetic field
   component we use the divergence free condition, i.e., we need to
   calculate normal direvatived perpendicular components; now we used
   the derivative calculation with the proper limiting in order to keep
   the consistency of the scheme;
 - in the interpolation module the new function has been added returning
   the limited derivative;

   coefficients will be transformed to real space for each block
   separately;

   ftab; this complex array will be used to calculate forcing in real
   space for each block;
