Wraps many Form subclases in order to get a form wizard to treat them as one.

Many Forms will use one step.

Example:

class LanguageVerifiedHumanForm(MultipleForms): base_forms = [ ('language_form', LanguageForm), ('verified_human_form', VerifiedHumanForm) ]

class NewGuideWizard(SessionWizardView): form_list = [ ('guide_form', GuideForm), ('multi_form', LanguageVerifiedHumanForm), ]
