d92ae5d3a6 INTERPOLATION: pass the spacial increment to reconstruct(). 
- pass the spacial increment to the reconstruction subroutine since
   some interpolation methods require it; in addition, move obtaining
   the spacial interval and its inversion to the subroutine update();

93a4617dee BOUNDARY, MPI: make boundary_variables() working with MPI. 
- implement the MPI version of subroutine boundary_variables(); right
   now we are sending full variable arrays between blocks, but this is
   not optimal; better version should exchange only subdomain needed for
   boundary update;

366e2ff610 BOUNDARY: add global variables for box periodicity. 
- add a global variable in the configuration module to determine if the
   boundaries are periodic along each direction; this flag is useful if
   we can skip some work which is only for non-periodic boundaries, such
   as applying specific boundary conditions;

0759b6b814 BOUNDARY: remove unnecessary update at the same level. 
- with all variables cell centered we do not need to perform additional
   update between blocks at the same level since now everything can be
   done at once; the only restriction is that the boundary update has to
   be done along each direction separately;
