Class in example for SingleTableMixin inherits from SingleTableView

[keikoro]

The code example for SingleTableMixin in the docs does not reference SingleTableMixin anywhere; what's shown is a class which inherits from SingleTableView:

django-tables2/docs/pages/generic-mixins.rst

Line 28 in 527c746

from django_tables2 import SingleTableView

django-tables2/docs/pages/generic-mixins.rst

Lines 41 to 43 in 527c746

	class PersonList(SingleTableView):
	model = Person
	table_class = PersonTable

The example for MultiTableMixin further down the page does include a class inheriting from MultiTableMixin.
