title: How to slice on arbitrary indices with breeze?
body: <p>In Python's numpy, I can do this:</p>
  
  <pre><code>&gt;&gt;&gt; import numpy as np
  &gt;&gt;&gt; m = np.array([[1,2,3,4],[5,6,7,8],[9,10,11,12]])
  &gt;&gt;&gt; indices = [1,3]
  &gt;&gt;&gt; m[:,indices]
  array([[ 2,  4],
         [ 6,  8],
         [10, 12]])
  </code></pre>
  
  <p>In other words, I can slice based on an arbitrary (not necessarily contiguous) list of indices.  How can I do something similar in Breeze?  I'm looking for something efficient and preferably elegant.</p>
