    A meta-decorator to apply swagger decorators for multiple methods.

    This decorator simplifies applying multiple decorators by applying sane defaults
    for swagger decorator, and passing in the supplied values as the summary.

    Example:
        @viewset_swagger_helper(
            list="List Snippets",
            create="Create new Snippet",
            destroy="Delete Snippet",
            public_actions=["list"]
        )
        class SnippetViewSet(ModelViewSet): ...

        In the above example this function will apply a decorator that will override
        the operation summary for `list`, `create` and `destroy` for the `SnippetViewSet`.
        The `public_actions` parameter specifies which actions don't need an authentication
        and as such won't raise an authentication/authorization error.
