title: Read returning parameters when calling a lua function using LuaInterface
body: <p>I am trying to handle the parameters returned from lua when I call DoString:</p>
  
  <pre><code>object[] retval = lua.DoString("some_lua_function()");
  </code></pre>
  
  <p>The luafunction returns nil, true or false as first parameter and a string as second parameter.</p>
  
  <p>What is the best way to receive the parameters as c# bool and string values?</p>
  
  <p>thank you very much!</p>
