Build a tridiagonal matrix block for finite differences. See the end of the documentation of the fin_diff_block type for a description of how boundary conditions are treated.

| integer, | intent(in), | optional | dimension(:) | :: | boundary_types | Integers specifying the type of boundary condition. The type
of boundary condition corresponding to a given integer is
specified in boundary_types_mod. Only Dirichlet and
Neumann conditions are supported. Defaults to Dirichlet. The
order in which they are stored must match that of
