feed-abstract 0.0.9

This library creates a common object graph for the RSS/Atom/RDF parsing classes in the ruby standard library. This allows you parse different feed formats and get back the same (or at least a very similar) set of results - item authors are accessible under an "author(s)" attribute, categories/tags/subjects are accessible under "category(ies)" attributes, etc. We do our best to make sure the data makes sense, too - RSS items lack an "updated" attribute, so we use "pubDate" to populate it.
