Iteration 1

Use TDD to create a Dish class that responds to the following interaction pattern:

pry(main)> require './lib/dish'
#=> true

pry(main)> dish = Dish.new("Couscous Salad", :appetizer)
#=> #<Dish:0x00007f93fe9aa698...>

pry(main)> dish.name
#=> "Couscous Salad"

pry(main)> dish.category
#=> :appetizer

Iteration 2

Use TDD to create a Potluck class that responds to the following interaction pattern:

pry(main)> require './lib/dish'
#=> true

pry(main)> require './lib/potluck'
#=> true

pry(main)> potluck = Potluck.new("7-13-18")
#=> #<Potluck:0x00007fccc4abe940...>

pry(main)> potluck.date
#=> "7-13-18"

pry(main)> potluck.dishes
#=> []

pry(main)> couscous_salad = Dish.new("Couscous Salad", :appetizer)
