/**
* Converts a DataModel into data suitable for use with the form. The difference to the Model's getData() method is
* that we process hasOne and belongsTo relations. This is a recursive function which will be called at most
* $maxLevel deep. You can set this in the form XML file, in the relation_depth attribute.
*
* The $modelsProcessed array which is passed in successive recursions lets us prevent pointless Inception-style
* recursions, e.g. Model A is related to Model B is related to Model C is related to Model A. You clearly don't
* care to see a.b.c.a.b in the results. You just want a.b.c. Obviously c is indirectly related to a because that's
* where you began the recursion anyway.
*
* @param DataModel $model The item to dump its contents into an array
* @param int $maxLevel Maximum nesting level of relations to process. Default: 1.
* @param array $modelsProcessed Array of the fully qualified model class names already processed.
*
* @return array
* @throws DataModel\Relation\Exception\RelationNotFound
