lduMatrix's implementation of the H operator.

$\boldsymbol \psi_n -= A_o \boldsymbol \psi_o$

$\boldsymbol \psi_o -= A_n \boldsymbol \psi_n$

Where:

A are matrix coefficients;
o and n are the owner and neighbour indices; and
$\boldsymbol \psi$ is the field variable of the matrix (a parameter, owned by fvMatrix).
