Currently the FamousPerson class defines the natural order of its elements to be based on the alphabetical order of people names (last name, then first name). It also provides a Comparator that defines order based on increasing year of birth. Augment the class to include more public static methods that return Comparators as described below. Augment the CSPeople application to demonstrate that the new Comparators work properly

a. Order alphabetically by name (first name, then last name)
b. Order by year of birth—decreasing
c. Order by length of "fact"—increasing
