title: Change/add create-react-app entry point or location of index.js
body: <p>I am trying to use create-react-app to create a simple web-app. I have moved the pages and components into separate directories under src labeled <code>pages</code> and <code>components</code>. I would like to change/add the entry point for index.js from src/index.js to src/pages/index.js. Another option would be to keep index.js in src/ and import from pages and component directories. Can someone help me to find how i can change the entry point path?</p>
  
  <p>I can't seem to find the location of the default html-webpack-plugin config file. </p>
  
  <p>Here is what I would like the structure to be:</p>
  
  <pre><code>(in src)
  ...
  pages/
     - App.js
     - Home.js
  
  components/
     - Filter.js
  
  serviceWorker.js
  </code></pre>
