Suppose you have a pre-existing class Food that represents items of food that can be eaten at a restaurant. The class has the following data and behavior:

private String kind kind of food such as "hamburger"
private double price price of this food item, such as 1.99
public Food(String kind, double price) makes a food item of the given kind and price
public String getKind() returns the kind of food
public double getPrice() returns the food item's price
public String toString() returns a String such as "hamburger: $1.99"

Your task is to modify the class to be Comparable by adding an appropriate compareTo method. Food items are ordered by the kind of food, case-insensitively. In other words, a food item of kind "Hamburger" comes before "pizza" which comes before "STEAK". If there are two food items of the same kind, they are compared by price, with less expensive food items considered "less than" more expensive ones. If two food items are of the same kind and have the same price, they are considered to be "equal." Your method should not modify the food item's state. You may assume the parameter passed is not null.
