title: Define Custom Scheme Handler for Chromium Embedded Framework using CEFPython
body: <p>How can one defines a custom scheme handler for CEF in Python using CEFPython?</p>
  
  <p>I've found this <a href="http://magpcss.org/ceforum/viewtopic.php?f=8&amp;t=32" rel="nofollow">thread</a> that explains how to define a <code>CefSchemeHandlerFactory</code> and <code>CefSchemeHandler</code> in C++. But I can't find out how should I employ <code>CefBase</code> as a base type to implement these classes in Python and where is the documentation for equivalent classes in Python.</p>
