title: eslint config for exp init project
body: <p>I was compiling perfect way for adding eslint-flow-prettier in all types of react native projects.
  I have some question about using eslint in Expo project. <br>
  Does exp init also install eslint?
  If not, I have tried using following command for installing eslint</p>
  
  <pre><code>1)yarn add --dev eslint eslint-config-airbnb eslint-plugin-import eslint-plugin-react eslint-plugin-jsx-a11y babel-eslint 
  
  2)yarn eslint --init
  </code></pre>
  
  <p><strong>Is this the correct way to put eslint in expo project?<br></strong>
  In the second step above it asked to <em>Select 'Use a popular style guide'</em>, I selected Airbnb, after that it removed multiple packages and project is not running(obvious reason for error: missing libraries).<br>So why this is happening?<br>Should I have selected config other than Airbnb?(only 3 options for eslint config: Google, Airbnb, Standard)</p>
  
  <p>Also I did use YARN for expo project because NPM was giving more complication, as it was removing 500+ packages during step1 above, which resulted in many of the libraries going missing from project, I tried npm install to install all packages but still had problems. So went with YARN.<br></p>
  
  <p>For now I want to somehow include eslint in the Expo project.<br></p>
  
  <p>Thanks in advance.</p>

  1)Here is the info after installing eslint using: <code>npm install --save-dev eslint-config-airbnb babel-eslint</code> (npm version 5.8.0)
