/**
* Implement this hook to create an alternative parser for aggregator module.
*
* A parser converts feed item data to a common format. The parser is called
* at the second of the three aggregation stages: data is downloaded by the
* active fetcher, it is converted to a common format by the active parser and
* finally, it is passed to all active processors which manipulate or store the
* data.
*
* Modules that define this hook can be set as the active parser on
* admin/config/services/aggregator. Only one parser can be active at a time.
*
* @param $feed
* An object describing the resource to be parsed: $feed->source_string
* contains the raw feed data. The hook implementation should parse this data
* and add the following properties to the $feed object:
* - description: The human-readable description of the feed.
* - link: A full URL that directly relates to the feed.
* - image: An image URL used to display an image of the feed.
* - etag: An entity tag from the HTTP header used for cache validation to
* determine if the content has been changed.
* - modified: The UNIX timestamp when the feed was last modified.
* - items: An array of feed items. The common format for a single feed item
* is an associative array containing:
* - title: The human-readable title of the feed item.
* - description: The full body text of the item or a summary.
* - timestamp: The UNIX timestamp when the feed item was last published.
* - author: The author of the feed item.
* - guid: The global unique identifier (GUID) string that uniquely
* identifies the item. If not available, the link is used to identify
* the item.
* - link: A full URL to the individual feed item.
*
* @return
* TRUE if parsing was successful, FALSE otherwise.
