+Exercise 33: Birthday Dictionaries
+
+This exercise is Part 1 of 4 of the birthday data exercise series.
+The other exercises are: Part 2, Part 3, and Part 4.
+
+For this exercise, we will keep track of when our friend’s birthdays
+are, and be able to find that information based on their name.
+Create a dictionary (in your file) of names and birthdays. When you
+run your program it should ask the user to enter a name, and return
+the birthday of that person back to them. The interaction should
+look something like this:
+
+>>> Welcome to the birthday dictionary. We know the birthdays of:
+Albert Einstein
+Benjamin Franklin
+Ada Lovelace
+>>> Who's birthday do you want to look up?
+Benjamin Franklin
+>>> Benjamin Franklin's birthday is 01/17/1706.
+Happy coding!
