'Parsers actors XML, from
http://thetvdb.com/api/[APIKEY]/series/[SERIES ID]/actors.xml
Actors are retrieved using t[\'show name][\'_actors\'], for example:
>>> t = Tvdb(actors = True)
>>> actors = t[\'scrubs\'][\'_actors\']
>>> type(actors)
<class \'tvdb_api.Actors\'>
>>> type(actors[0])
<class \'tvdb_api.Actor\'>
>>> actors[0]
<Actor "Zach Braff">
>>> sorted(actors[0].keys())
[\'id\', \'image\', \'name\', \'role\', \'sortorder\']
>>> actors[0][\'name\']
u\'Zach Braff\'
>>> actors[0][\'image\']
u\'http://thetvdb.com/banners/actors/43640.jpg\'
Any key starting with an underscore has been processed (not the raw
data from the XML)'
