title: Adding records to a numpy record array
body: <p>Let's say I define a record array</p>
  
  <pre><code>&gt;&gt;&gt; y=np.zeros(4,dtype=('a4,int32,float64'))
  </code></pre>
  
  <p>and then I proceed to fill up the 4 records available.  Now I get more data, something like</p>
  
  <pre><code>&gt;&gt;&gt; c=('a',7,'24.5')
  </code></pre>
  
  <p>and I want to add this record to <code>y</code>.  I can't figure out a clean way to do it.  The best I have seen in <code>np.concatenate()</code>, but that would require turning <code>c</code> into an record array in and of itself.  Is there any simple way to tack my tuple <code>c</code> onto <code>y</code>?  This seems like it should be really straightforward and widely documented.  Apologies if it is.  I haven't been able to find it.</p>
