create stub nested partial views. show event shows links to belongs_to fields
automatic nested partial views. only show and index implemented. shows query fields on model class in index view
eventsController#index has custom index method to preload nested objects. need to generalize. id's are no longer shown, but instead using display_name on each object
removed event controller optimization and put as comment in application controller #index method
notes. no code
changed to using postgres database
