Helper base class that picks principal ids.
Add numbers to ids given by users to make them unique.
The Id picker is a variation on the name chooser that picks numeric ids when no name is given.
>>> from zope.app.authentication.idpicker import IdPicker >>> IdPicker({}).chooseName('', None) u'1'>>> IdPicker({'1': 1}).chooseName('', None) u'2'>>> IdPicker({'2': 1}).chooseName('', None) u'1'>>> IdPicker({'1': 1}).chooseName('bob', None) u'bob'>>> IdPicker({'bob': 1}).chooseName('bob', None) u'bob1'

True
>>> IdPicker({}).checkName(u'bob', None)
True
>>> IdPicker({}).checkName(u'bobú', None)
... # doctest: +NORMALIZE_WHITESPACE

... # doctest: +NORMALIZE_WHITESPACE

True
>>> IdPicker({}).checkName(u'x' * 101, None)
