We are working with double precision, so this subroutine should return a
real value with double precision too.

In 2D we don't have face neighbor pointers, so we have to use edge
neighbor pointers to find those which are not associated, so we can
apply specific boundary conditions. This fixes the calculation of
the edge neighbor direction.

This is 5th order compact reconstruction using implicit solver and
characterized by 10 time smaller errors comparing to explicit 5th order
WENO reconstruction.
Several methods to calculate stencil weights have been added too.

We need to nullify parent's neighbor pointers after finishing its
refinement process, otherwise they can point to unallocated blocks
causing the failure of job restart.

Now we calculate the refinement criterion over a region which is larger
than the block domain by one cell. It should allow to detect incoming
gradients earlier and result in gradents entering the already
refined block.

This debuggin fuctions checks face, edge, and corner pointers and check
the corresponding pointers of the pointed neighbors, if they are
consistent, i.e. if they point to each other.

All subroutines which use %neigh field of meta block have been removed,

This patch rewrites two subroutines boundary_fluxes() and related
block_update_flux() in order to use new pointers (faces in 3D and edges
in 2D). It also signficantly simplifies block_update_flux() comparing to
previous version correct_flux().

This update of 2D neighbor' pointers for derefined block iterates
over corners instead of updating each neighbor's pointer
explicitely. It updates both, edge and corner neighbor pointers
of connected neighbors at once.

If we refine a block, and the neighbor lays at the same level of the
parent, do not assign the child's interior corner pointer. Those
pointers are null then.
This is not a problem for corner boundary update, since this corner
is updated in boundaries_edge_prolong, therefore all corners of the
finer blocks are fully consisten with their neighbors.
This also removes unnecessary condition check in
boundaries_corner_prolong().
