/// <summary>
/// This example uses the Abstract Factory creational pattern to help fulfill a meal planning application
/// for customers who wish to follow a specific type of diet. Depending on the customer's diet,
/// a different Meal Plan is generated, which contains methods in this example for generating lunch or dessert menus,
/// which provide lists of ingredients, meals, and diet summaries.
/// One of the benefits of this approach is that all of the data associated with a specific diet,
/// such as the foods involved in meal prep and grocery lists, can belong to specific factories,
/// increasing the ability to ensure compatibility across the various products of a MealPlanFactory.
/// One of the downsides of this approach is that it is fairly complex for small use cases, though
/// it does promote extensibility (Open / Closed principle - open for extension, closed for modification)
/// if new meal plans are introduced, there is no need clients of the MealPlanService.
