incorrect warning for pandas.io.pytables.HDFStore()
calling pandas.io.pytables.HDFStore() function (or its alias pd.HDFStore) will generate the following warnings in pandas 0.17, which is incorrect since HDFStore is not part of pandas.io.data or pandas-datareader package.

The pandas.io.data module is moved to a separate package (pandas-datareader) and will be removed from pandas in a future version.
After installing the pandas-datareader package (https://github.com/pydata/pandas-datareader), you can change the import `from pandas.io import data, wb` to `from pandas_datareader import data, wb`.
  FutureWarning)
