"""Build and return a :class:`colander.SchemaNode` for a relationship.
The mapping process will translate one-to-many and many-to-many
relationships from SQLAlchemy into a ``Sequence`` of ``Mapping`` nodes
in Colander, and translate one-to-one and many-to-one relationships
into a ``Mapping`` node in Colander. The related class involved in the
relationship will be recursively mapped by ColanderAlchemy as part of
this process, following the same mapping process.
This method uses information stored in the relationship within
the ``info`` that was passed to the relationship on creation.
This means that ``Colander`` options can be specified
declaratively in ``SQLAlchemy`` models using the ``info``
argument that you can pass to
:meth:`sqlalchemy.orm.relationship`.
For all relationships, the settings will only be applied to the outer
Sequence or Mapping. To customise the inner schema node, create the
attribute ``__colanderalchemy_config__`` on the related model with a
dict-like structure corresponding to the Colander options that should
be customised.
