Write a public static method named average which takes an ArrayList of Double objects, and returns the average of the values in this list. Write your average method in the U7_L2_Activity_Two class. Use the runner class to test your method but do not add a main method to the U7_L2_Activity_Two.java file or your code will not be scored correctly.

Hint: when you write your method header, and specify the type of the parameter as an ArrayList, make sure you include the data type your ArrayList will contain in angle brackets (<>).
