title: How do you pull child and parent issues using the GitHub API or PyGithub?
body: <p>In Github, you have the option of referencing issues within an issue. For example, I can make an epic which in turn acts as the parent of n number of child issues I create.</p>
  
  <p>Is there a way to pull linked issues using the <a href="https://developer.github.com/v3/issues/#list-issues" rel="nofollow noreferrer">Github API</a> or <a href="https://pygithub.readthedocs.io/en/latest/index.html" rel="nofollow noreferrer">PyGithub</a>?</p>
  
  <p>I am able to pull details such as title, state, login_name, issue number, etc. using the API, but cannot figure out how to pull linked issues without writing a complex script that parses through the content of the body. </p>
