title: Get list of Functions from NLua
body: <p>I am using NLua for script interface with my application
  if my application takes multiple files such as one.lua and two.lua</p>
  
  <p>i want to get all the functions in all files in to a list of luafunctions</p>
  
  <pre><code>List&lt;LuaFunctions&gt; Functions;
  </code></pre>
  
  <p>NLua doesnt seem to have such a feature, but is there a way around it,
  there is a GetFunction(string) methodthat will return the function that you named,
  i can ofc do a brute force method on the GetFunction method but that will make my application take hours to start up with.</p>
  
  <p>Any ways to work around this and get all functions in all files to a list of luafunctions?</p>
