Resource relationships

[nickrigby]

In restful it's possible to define a relationship with a resource e.g.

$public_fields['band'] = array( 'property' => 'field_band', 'resource' => array( 'name' => 'band', 'majorVersion' => '1', 'minorVersion' => '0', ), );

However, this doesn't appear to work with the restful_search_api module. Is there any way to implement this? Many thanks for a great module!
