title: How to change git url for app on Heroku
body: <p>When I run "git remote -v" from Terminal I get the following:</p>
  
  <pre><code>heroku  git@heroku.com:obscure-taiga-9581.git (fetch)
  heroku  git@heroku.com:obscure-taiga-9581.git (push)
  origin  http://coastguard-quiz.herokuapp.com/ (fetch)
  origin  http://coastguard-quiz.herokuapp.com/ (push)
  </code></pre>
  
  <p>I want to replace the "git@heroku.com:obscure-taiga-9581.git" part. How do I do that?</p>
