Embed stat card into form

[occoder]

I'd like to group stat cards into form and tried to implement it using
the_form = ui.form_card(box='1 1 4 -1', items=[ui.small_stat_card(title='demo', value='1000')])
But it turned out reflecting message like
This component could not be rendered.
So the question is what is the appropriate way to make group of stat cards?
Thanks

@occoder Currently it's not possible to include stats cards inside a form_card (or in general, include one card inside another). This will be addressed by #147.

Related: a ui.stats() component API will be out in the next release, which will support displaying simple label/value pairs inline in a form, via 3fd1956
