// Description:		TPriceGraphConstructor is a concrete base class for
//					objects that set up a TStandardGraph object to display
//					stock price information.
//
//					TAllDaysPriceGraphConstructor is a concrete class which
//					sets up a TStandardGraph to show stock price information
//					for every TStockDay object in the stock data collection.
//					TMonthlySummaryPriceGraphConstructor shows stock price
//					information grouped into summaries of each month's trading.
//					TWeeklySummaryPriceGraphConstructor shows stock price
//					information grouped into summaries of each week's trading.
//
//					TVolumeGraphConstructor is a concrete base class for
//					objects that set up a TStandardGraph object to display
//					stock trading volume information.
//
//					TAllDaysVolumeGraphConstructor is a concrete class which
//					sets up a TStandardGraph to show stock trading volumes
//					for every TStockDay object in the stock data collection.
//					TMonthlySummaryPriceGraphConstructor shows trading volume
//					information grouped into summaries of each month's trading.
//					TWeeklySummaryPriceGraphConstructor shows trading volume
//					information grouped into summaries of each week's trading.
