title: Load Lua-files by relative path
body: <p>If I have a file structure like this:</p>
  
  <pre><code>./main.lua
  ./mylib/mylib.lua
  ./mylib/mylib-utils.lua
  ./mylib/mylib-helpers.lua
  ./mylib/mylib-other-stuff.lua
  </code></pre>
  
  <p>From <code>main.lua</code> the file <code>mylib.lua</code> can be loaded with full path <code>require('mylib.mylib')</code>. But inside <code>mylib.lua</code> I would also like to load other necessary modules and I don't feel like always specifying the full path (e.g. <code>mylib.mylib-utils</code>). If I ever decide to move the folder I'm going to have a lot of search and replace. Is there a way to use just the relative part of the path?</p>
  
  <p>UPD. I'm using Lua with Corona SDK, if that matters.</p>
