/**
* Implementation of feed element mapper for location.module.
*/

/**
* Implementation of hook_feedapi_mapper().
* Maps feed elements to location fields.
* @param $op
*   'list' or 'map'
* @param $node
*   Feed item node to map on.
* @param $field_name
*   Name of field to map to.
* @param $feed_element
*   Feed item element to map from. Parameter only present on $op = 'map'
* @param @sub_field
*   Subfield on field to map to. Parameter only present on $op = 'map'.
*   This parameter will depend on if the hook implementation returns a subfield on
*   $op = 'list'.
*
* Return key => name array of sub fields on 'list'.
* If only one field and no subfields are available for this content type return TRUE.
* If no fields available for this content type return FALSE.
* Options are necessary because a field like
* e. g. "taxonomy" might have more than one slot for information - e. g. vocabularies.
*
* Todo: $node could be passed by reference - implementers wouldn't need to return node
* (PHP5 passes in by reference by default).
