def add_boundary_pores(self, labels, spacing):
r"""
Add boundary pores to the specified faces of the network
Pores are offset from the faces by 1/2 of the given ``spacing``, such
that they lie directly on the boundaries.
Parameters
----------
labels : string or list of strings
The labels indicating the pores defining each face where boundary
pores are to be added (e.g. 'left' or ['left', 'right'])
spacing : scalar or array_like
The spacing of the network (e.g. [1, 1, 1]). This must be given
since it can be quite difficult to infer from the network,
for instance if boundary pores have already added to other faces.
