Include a default argument for an initialize argument.
Overview
You're going to be building a Person class that accepts a person's name when a person is initialized. You're also going to be building a Dog class that accepts a dog's name and breed on initialization. If no value for the dog's breed is provided, it should default to "Mutt"
Instructions
Open this lab with learn open and run the tests with learn.
1. Person#initialize with a Name
Define a Person class in lib/person.rb that provides an #initialize method that accepts an argument for the person's name. That argument should be stored within a @name instance variable.
2. Dog#initialize with Name and Breed defaulting to "Mutt"
Define a Dog class in lib/dog.rb that provides an #initialize method that accepts an argument for the dog's name. That argument should be stored within a @name instance variable.
Additionally, Dog#initialize should accept a second optional argument for the dog's breed stored in an instance variable @breed. When none is provided, it should default to "Mutt".
