function party_views_data in Party 8.2

Same name and namespace in other branches

1. 7 includes/views/party.views.inc \party_views_data()

Implements hook_views_data().

We can implement this *and* get entity module's views data for free because we set our entity's 'views controller class' in hook_entity_info().
