Atom feed class
The Horde_Feed_Atom class is a concrete subclass of the general Horde_Feed_Base class, tailored for representing an Atom feed. It shares all of the same methods with its parent. The distinction is made in the format of data that Horde_Feed_Atom expects, and as a further pointer for users as to what kind of feed object they have been passed.
