SimilarPersons ready for customer review
----------------------------------------

SimilarPersons has now `slave_grid_format` = 'summary'.  Fixed a bug
in the framework which made that Lino didn't yet manage this case
(setting `slave_grid_format` to "summary" on a VirtualTable).

The algorithm for finding similar persons isn't yet very intelligent,
but at least we have now an integral workflow to cope with the problem
of duplicate new clients. Great!  SimilarPersons is ready for customer
review.


Aid regimes, Aid helpers
------------------------

Added some new tables in :mod:`lino_welfare-modlib.aids`. This is my
favourite suggestion about how to store these information. To be
tested and analyzed with end-users.

Checkin. 

Also discovered a very subtle pitfall:

When inserting to MedicalAidsByClient and then (in the Insert window)
opening the ComboBox for the `aid_type` field, Lino displayed *all*
AidType objects (also financial ones).  This was not correct since
`get_known_values` sets `aid_regime` to a non-None value.

In fact already the ajax call used to get that choicelist was wrong,
it went to `/choices/aids/AidsByClient/aid_type` instead of
`/choices/aids/MedicalAidsByClient/aid_type`.

This is was solved by a workaround: We define `insert_layout` on both
subclasses of AidsByClient, not on the base class.  This is not
logical since they are the same, but necessary due to the current
implementation of combobox fields. The url from which a combobox field
gets its data is a hard-coded constant in the (generated) JS code.  If
you don't duplicate the insert_layout, then Lino will generate only
one ExtJS definition of the InsertWindow, common to all
subclasses. See :class:`lino.ui.elems.ForeignKeyElement`
and :class:`lino.ui.elems.RemoteComboFieldElement`

Note that this trick of using an `_aid_regime` class attribute 
(in :mod:`lino_welfare.modlib.aids.models.AidsByClient`)
as only
difference between those two tables is rather special.  It is also
being used for differentiating between "Studies" and "Trainings".
Usually I recommend to define two different models (and use an
abstract model mixin for their common parts). But these cases are not
usual.
