Now uses OOP where it fits. Atom feeds are supported, but no real tests were made. Unix globbing is now possible for urls. Caching is done a cleaner way. Feedburner links are also replaced. HTML is cleaned a more efficient way. Code is now much cleaner, using lxml.objectify and a small wrapper to access Atom feeds as if they were RSS feeds (and much faster than feedparser). README has been updated.
This is a huge commit. The whole code is ported to Object-Oritented Programming. This makes the code cleaner, which became required to deal with all the different cases, for example with encoding detection. Encoding detection now works better, and uses 3 different methods. HTML pages with an xml declaration are now supported. Feed urls with parameters (eg. "index.php?option=par") are also supported. Cache is now smarter, since it no longer grows indefinitely, since only in-use pages are kept in the cache. Caching is now mandatory. urllib (not urllib2) is no longer needed. Solved a possible crash with log function (when passing list of str with non-unicode encoging).
README is also updated.
