Code update.

1.  Changed the default 'start' date used by GET_DATA_GOOGLE to one that
    ensures the complete set of historic price data is returned.

Issue 8 fix.

Date:               21 August 2014
Details:            The default 'start' date, which is set to the beginning
                    of the Unix epoch, does not result in the complete set
                    of historic price data being returned for all symbols.
