title: mpl_finance module import error in python
body: <p>I have tried using <code>from matplotlib.finance import quotes_historical_yahoo_ochl</code> but found that it is deprecated. Hence, I have installed <code>mpl_finance</code> and tried this:  </p>
  
  <pre><code>from mpl_finance import quotes_historical_yahoo_ochl
  </code></pre>
  
  <p>But I got the following error:  </p>
  
  <pre><code>ImportError: cannot import name 'quotes_historical_yahoo_ochl'
  </code></pre>
  
  <p>I thought to check it:   </p>
  
  <pre><code>dir(mpl_finance)
  </code></pre>
  
  <p>And found the following:  </p>
  
  <pre><code>['Affine2D', 'Line2D', 'LineCollection', 'PolyCollection', 'Rectangle', 'TICKLEFT', 'TICKRIGHT', '__builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__spec__', '_candlestick', '_check_input', '_plot_day_summary', 'absolute_import', 'candlestick2_ochl', 'candlestick2_ohlc', 'candlestick_ochl', 'candlestick_ohlc', 'division', 'index_bar', 'mcolors', 'np', 'plot_day_summary2_ochl', 'plot_day_summary2_ohlc', 'plot_day_summary_oclh', 'plot_day_summary_ohlc', 'print_function', 'unicode_literals', 'volume_overlay', 'volume_overlay2', 'volume_overlay3', 'xrange', 'zip']
  </code></pre>
  
  <p>Kindly, help me get rid of this issue. Please.</p>
