title: Pandas datetools module error
body: <p>I'm trying to call a module from pandas datetools, but am getting an error that the mofule object has no attribute by the name I'm calling. Wondering if anyone can shed some light on this issue. Below is the code I am trying to use:</p>
  
  <pre><code>import blpapi
  import pandas as pd
  from tia.bbg import LocalTerminal
  import datetime
  from pandas import datetools
  
  sid = 'BKLN US EQUITY'
  events = ['TRADE','AT_TRADE']
  dt = pd.datetools.BDAY(-1).apply(pd.datetime.now())
  </code></pre>
  
  <p>And here is the error I am facing:</p>
  
  <pre><code>Traceback (most recent call last):
  File "C:\bb_test.py", line 14, in &lt;module&gt;
  dt = pd.datetools.BDAY(-1).apply(pd.datetime.now())
  File "C:\Python27\lib\site-packages\pandas\util\_depr_module.py", line 61, in 
  __getattr__
  obj = getattr(deprmodule, name)
  AttributeError: 'module' object has no attribute 'BDAY'
  </code></pre>
