aqt-base

In my search for a reliable provider of historical quotes I ran into an interactive charting tool at www.bigcharts.com. The applet caught my eye because it had a lot of useful information: splits, dividends, earnings and technical indicators. I looked at the http traffic and realized that it receives from the server even more data: date, open, high, low, close, volume, adjustedClose, sharesOutstanding, rollingEarnings, shortInterest, earnings, earningsDelta, dividend, rollingDividends, bid, ask. Another type of a request can return historical market statistics: date, advancers, decliners, unchanged, countActive, volatilityAdvancers, volatilityDecliners.

May be some day we will implement market data entities for splits, dividends, earnings, and even news. But for now I implemented just a simple candle source for this provider.

I attached a BigChartsCandleSeriesSource class and a set of unit tests. Unfortunately, these tests have to be updated every time IBM has a dividend or a split. Please note, that one of the tests fails because of the problem with the alignCalendar() method (see BUG-31).

Please review and add to the code base.
