docs: Load some seed data. There are two ways to do this.
  
   Verbose syntax
   --------------
  
   This will seed a single record. The `:id` parameter ensures that if a record already exists
   in the database with the same id, then it will be updated with the name and age, rather
   than created from scratch.
  
       Person.seed(:id) do |s|
         s.id   = 1
         s.name = "Jon"
         s.age  = 21
       end
  
   Note that `:id` is the default attribute used to identify a seed, so it need not be
   specified.
  
   Terse syntax
   ------------
  
   This is a more succinct way to load multiple records. Note that both `:x` and `:y` are being
   used to identify a seed here.
  
       Point.seed(:x, :y,
         { :x => 3, :y => 10, :name => "Home" },
         { :x => 5, :y => 9,  :name => "Office" }
       )
