title: Numpy genfromtxt Column Names
body: <p>How can I have <code>genfromtxt</code> to return me its <code>list</code> of column names which were automatically retrieved by <code>names=True</code>? When I do:</p>
  
  <pre><code>data = np.genfromtxt("test.csv",names=True,delimiter=",",dtype=None)
  print data['col1']
  </code></pre>
  
  <p>it prints the entire column values for <code>col1</code>. </p>
  
  <p><strong>However, I need to traverse all column names. How can I do that?</strong> </p>
  
  <p>I tried <code>data.keys()</code> and various other methods, but whatever is returned by <code>genfromtxt</code> does not seem to be a dictionary compatible object. I guess I could pass the <code>list</code> of column names myself, but this won't be maintainable for me in the long run.  </p>
  
  <p>Any ideas? </p>
