In this restaurant, the order will be returned with the main as first, the side as second and the drink as third
MANDATORY_COURSE is a dictionary where the keys is the meal you want and the value is a list of the course that must be ordered with the meal. In this restaraunt, every meal must have a main and side course ordered.
To add the to the menu, first create a mapping in the COURSE_CATEGORY_MAPPING for the specific course. The set the number mapping to a food item in the Menu dictionary. Feel free to add to COMPLIMENTARY and SINGLE_ITEM if you need to make adjustments. For example, this restaurant now wants to add Crab Cakes as an appetizer to its list of options for dessert. The following environment variables will be set:
MENU="{\"breakfast\":{\"1\":\"Eggs\",\"2\":\"Toast\",\"3\":\"Coffee\"},\"lunch\":{\"1\":\"Sandwich\",\"2\":\"Chips\",\"3\":\"Soda\"},\"dinner\":{\"1\":\"Steak\",\"2\":\"Potatoes\",\"3\":\"Wine\",\"4\":\"Cake\", \"5\":\"CrabCakes\"}}"

SINGLE_ITEM="{\"breakfast\":[\"1\",\"2\"],\"lunch\":[\"1\",\"3\"],\"dinner\":[\"1\",\"2\",\"3\"]}"

COURSE_CATEGORY_MAPPING="{\"main\":\"1\",\"side\":\"2\",\"drink\":\"3\",\"dessert\":\"4\", \"appetizers\":\"5\"}"

MANDATORY_COURSE="{\"breakfast\":[\"main\",\"side\"],\"lunch\":[\"main\",\"side\"],\"dinner\":[\"main\",\"side\",\"dessert\"]}"
