Provides access to an element's class attribute as a set-like collection. Usage:

>>> el = fromstring('<p class="hidden large">Text</p>')
>>> classes = el.classes  # or: classes = Classes(el.attrib)
>>> classes |= ['block', 'paragraph']
>>> el.get('class')
'hidden large block paragraph'
>>> classes.toggle('hidden')
False
>>> el.get('class')
'large block paragraph'
>>> classes -= ('some', 'classes', 'block')
>>> el.get('class')
'large paragraph'
