Quiz-7 Grade School

Write a small archiving program that stores students along with the grade that they are in.

school = School.new("Haleakala Hippy School")

If no students have been added, the db should be empty:

school.db
# => {}

When you add a student, they get added to the correct grade.

school.add("James", 2)
school.db
# => {2 => ["James"]}

You can, of course, add several students to the same grade, and students to different grades.

school.add("Phil", 2)
school.add("Jennifer", 3)
school.add("Little Billy", 1)
school.db
# => {2 => ["James", "Blair"], 3 => ["Jennifer"], 1 => ["Little Billy"]}

Also, you can ask for all the students in a single grade:

school.grade(2)
# => ["James", "Blair"]

extension

Lastly, you should be able to get a sorted list of all the students. Grades are sorted in descending order numerically, and the students within them are sorted in ascending order alphabetically.

school.sort
# => {1 => ["Little Billy"], 2 => ["Blair", "James"], 3 => ["Jennifer"]}
