I continued to work on the LETS tutorial (:ref:`dev.lets`).
I added a branch "step2" and a section :ref:`dev.lets.step2`.
I added a branch "step3" and a section :ref:`dev.lets.step3`.

Internal optimizations:

- :meth:`lino.core.site.Site.setup_quicklinks` no longer searches and executes a
  global function :func:`setup_quicklinks` in each plugin, but calls the new
  plugin method :meth:`lino.core.plugin.Plugin.get_quicklinks`.

- :meth:`lino.core.model.Model.get_simple_parameters` may now yield an iterator of
  a series of fields. Until now the application developer had to write::

    @classmethod
    def get_simple_parameters(cls):
        for f in super(Demand, cls).get_simple_parameters():
            yield f
        yield "customer"
        yield "customer__place"

Now they can write more intuitively::

    @classmethod
    def get_simple_parameters(cls):
        yield super(Demand, cls).get_simple_parameters()
        yield "customer"
        yield "customer__place"


TODO: review the :class:`UserDetail` layout (in all three steps). There is
"design problem": the LETS tutorial is in the Developer Guide but it requires a
Contributor environment.
