title: how to create a custom layout in sublime text 2?
body: <p>I would like to create a 2 column layout where column 2 is split into 2 rows but havent really had any joy trying to find out how this can be done. I know that this layout gets added to Main.sublime-menu so I duplicated one of the layouts and called it Custom 1, not sure what I have to add in as the key/value pairs or array though. Could anyone possibly help me with this?</p>
  
  <p>here is what im working with so far:</p>
  
  <pre><code>{
                          "caption": "Custom 1",
                          "command": "set_layout",
                          "args":
                          {
                              "cols": [0.0, 0.5, 1.0],
                              "rows": [0.0, 0.5, 1.0],
                              "cells": [[0, 0, 1, 1], [0, 1, 1, 2], [0, 2, 1, 3]]
                          }
                      }
  </code></pre>
