"""Exercise 35: Birthday Months

This exercise is Part 3 of 4 of the birthday data exercise series. The
other exercises are: Part 1, Part 2, and Part 4.

In the previous exercise we saved information about famous scientists’
names and birthdays to disk. In this exercise, load that JSON file from
disk, extract the months of all the birthdays, and count how many
scientists have a birthday in each month.

Your program should output something like:

{
    "May": 3,
    "November": 2,
    "December": 1
}
