Ticker events could be lost in the StockTradingData class

[ishanthilina]

StockTradingData class has the method,

    public HashMap<Date, HashMap<TradingDataAttribute, Float>> getTradingData();

If two events have the same time stamp, they could be lost.

I know that we should not go in to that much resolution at the moment. But documenting this for the future references.
