title: Use arbitrary wx objects as a column in a wx.ListCtrl
body: <p>I have a <code>wx.ListCtrl</code> that has the <code>wx.LC_REPORT</code> bit set. It has 3 columns. I want the first column to be populated with a check box for each other entry. I tried using the <code>ListCtrl.InsertItem</code> method, but it only takes one argument (<code>info</code>) and I can't find any docs as to what that argument needs to be. I've tried just passing a <code>wx.CheckBox</code> to <code>InsertItem</code> to no avail.</p>
  
  <p>Is it possible to have a checkbox as an entry in a wxPython ListCtrl? If so, how would I go about doing that?</p>
  
  <p>In case there's any ambiguity as to what I'm talking about, here's a picture of what I want (not sure if this is wx, but it's what I'm looking for). I want the checkboxes next to 1..5 in the No. column.</p>
