Get timeline models up

I think our base components are "Events" (wedding) as the wrapper.

Each event has many "Activities" (prep, do hair, serve appetizer, etc)

Events = {
  id: eventId
  userId: owner UserId -- we can upgrade this to collaborative userIds in the future via mapping table (eventUsers table)
  name: string
  date: date
}

Activity = {
  id: activityId
  time: 0000 to 2359. Assumption here is that no event goes cross day? Or timestamp here...
  people: comma delimited people / people groups
}
