title: Python error when importing image_to_string from tesseract
body: <p>I recently used tesseract OCR with python and I kept getting an error when I was trying to import <code>image_to_string</code> from tesseract.</p>
  
  <p>Code causing the problem:</p>
  
  <pre><code># Perform OCR using tesseract-ocr library
  from tesseract import image_to_string
  image = Image.open('input-NEAREST.tif')
  print image_to_string(image)
  </code></pre>
  
  <p>Error caused by above code:</p>
  
  <pre><code>Traceback (most recent call last):  
  file "./captcha.py", line 52, in &lt;module&gt;  
  from tesseract import image_to_string  
  ImportError: cannot import name image_to_string
  </code></pre>
  
  <p>I've verified that the tesseract module is installed:</p>
  
  <pre><code>digital_alchemy@roaming-gnome /home $ pydoc modules | grep 'tesseract'
  Hdf5StubImagePlugin _tesseract          gzip                sipconfig
  ORBit               cairo               mako                tesseract
  </code></pre>
  
  <p>I believe that I've grabbed all the required packages but unfortunately I'm just stuck at this point.  It appears that the function is not in the module.</p>
  
  <p>Any help greatly appreciated.</p>
