Defines an interface for aggregator fetcher implementations.
A fetcher downloads feed data to a Drupal site. The fetcher is called at the first of the three aggregation stages: first, data is downloaded by the active fetcher; second, 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.
