Refactoring Ruby Gem Code & Adding Custom Errors (Let's Build a Ruby Gem, Ep 02)

In this episode, I refactor the `Converty.convert` method's implementation to be more resilient and support more distance units, introduce errors with helpful messages, and add the ability to convert between ounces and pounds. All of this is driven out by test-first RSpec tests. While the gem functionality is still early on and not complete, I think this episode encapsulates the development flow of expanding functionality. This episode is much more focused on writing and refactoring Ruby code than building a Ruby gem. Future episodes will return to working on and managing a gem, as well as coding more functionality.
