title: Lua referencing a file from a folder in the parent directory
body: <p>Using Love2d, I would like to load in an image that is located in a folder found in the parent directory.</p>
  
  <pre><code>Project
  &gt; code
  &gt;&gt; main.lua
  &gt; resources
  &gt;&gt; placeholderImage.jpg
  </code></pre>
  
  <p>What is the proper way to reference the parent directory?
  </p>
  
  <pre><code>function love.load()
    image = love.graphics.newImage("../resources/placeholderImage.jpg");
  end
  </code></pre>
