The FeedGenerator supports extension to include additional data into the
XML structure of the feeds. Extensions can be loaded like this::
>>> fg.load_extension('someext', atom=True, rss=True)
>>> fg.load_extension('someext', atom=True, rss=True)
This will try to load the extension “someext” from the file
`ext/someext.py`. It is required that `someext.py` contains a class named
“SomextExtension” which is required to have at least the two methods
`extend_rss(...)` and `extend_atom(...)`. Although not required, it is
strongly suggested to use BaseExtension from `ext/base.py` as superclass.

`load_extension('someext', ...)` will also try to load a class named
“SomextEntryExtension” for every entry of the feed. This class can be
located either in the same file as SomextExtension or in
`ext/someext_entry.py` which is suggested especially for large extensions.

`ext/someext_entry.py` which is suggested especially for large extensions.
The parameters `atom` and `rss` tell the FeedGenerator if the extensions
should only be used for either ATOM or RSS feeds. The default value for both
parameters is true which means that the extension would be used for both
kinds of feeds.

>>> from feedgen.feed import FeedGenerator

Of cause the extension has to be loaded for the FeedEntry objects as well
but this is done automatically by the FeedGenerator for every feed entry if
the extension is loaded for the whole feed. You can, however, load an
extension for a specific FeedEntry by calling `load_extension(...)` on that
entry. But this is a rather uncommon use.

Of cause you can still produce a normal ATOM or RSS feed, even if you have
loaded some plugins by temporary disabling them during the feed generation.
This can be done by calling the generating method with the keyword argument
`extensions` set to `False`.
