cookbook.rb

# Implement a `Cookbook` class which will act as fake database.
# It should implement 4 methods:
# - `initialize(csv_file_path)` which loads existing `Recipe` from the CSV
# - `all` which returns all the recipes
# - `add_recipe(recipe)` which adds a new recipe to the cookbook
# - `remove_recipe(recipe_index)` which removes a recipe from the cookbook.
