Add Examples to Repo

Description of the feature

Summary

There are currently no usage examples in the repo. We'd like to add an examples directory that contains examples of how to use this library. These should 1:1 follow the examples from our docs page to ensure consistency. Each object should have its own folder and then each file should be an action for that object (eg: create_address.rb, retrieve_address.rb, etc). Env vars should be used instead of an API key

Acceptance Criteria

• Add an examples dir with sub directories named after each object (lowercased)
• Each action you can take with the API gets a simple vanilla example
