Database data download tasks:
Downloads Quandl data based on the download selection criteria using either
the official Quandl Codes or implied codes from CSI Data.
Downloads Google Finance minute stock data.
Can either append only the new data, or replace part of the existing data.
Future expansions:
Implement daily option chain data (from Google or Yahoo).
