Requirements

I want a program that I can load in IRB that allows me to

• Store all of my friends’ birthdays so I can keep track of them
• See them all at once with their names and birthdays each on a line in a tidy format
• Check whose birthday it is today - the program can check through the birthdays I have stored and check each one to see if it’s someone’s birthday, and tells me something like "It's Mary Poppin's birthday today! They are 124 years old!" - otherwise it won't say anything.

More requirements:

• Test-drive extracting a birthday class
• Isolate your birthday list class using a mock for Birthday
