title: How could I read config in ipython notebook?
body: <p>I'm using anaconda 2.1 distributive.
  I had created my own config section </p>
  
  <pre><code>from IPython.config.configurable import Configurable
  from IPython.utils.traitlets import Int, Float, Unicode, Bool
  
  class Myconfig(Configurable):
      token = ""
  </code></pre>
  
  <p>Then initialization</p>
  
  <pre><code>c = get_config()
  load_subconfig('Myconfig.py')
  c.Myconfig.token='Somethingusefull'
  </code></pre>
  
  <p>How could I read Myconfig.token in notebook? </p>
  
  <p>Thanks!</p>
