                       # For numbers use Long or Double

  instance.save
  instance.key

  instance.foo
  instance.foo=

  Query.count
  Query.run -> Model[]
  Query.first -> instance || nil
  Query.sort(property_name)
  Query.sort(property_name, true) # descending
  Query.foo('foo').bar(3)  # Only return instances where foo = 'foo' and bar = 3
  Query.offset(10)
  Query.limit(5)
