docs: Map a selectable directly.
  
          The class and its mapping are not cached and will
          be discarded once dereferenced (as of 0.6.6).
  
          :param selectable: an :func:`.expression.select` construct.
          :param base: a Python class which will be used as the
            base for the mapped class. If ``None``, the "base"
            argument specified by this :class:`.SQLSoup`
            instance's constructor will be used, which defaults to
            ``object``.
          :param mapper_args: Dictionary of arguments which will
            be passed directly to :func:`.orm.mapper`.
