// .NET StockTrader Sample WCF Application for Benchmarking, Performance Analysis and Design Considerations for Service-Oriented Applications
// Note that for quotes we use in-page script to generate our repeating data for the HTML (based on the List
// returned of QuoteDataUI elements); vs. using databound Repeater controls as we do in the AccountOrders
// (control), Portfolio (page), and MarketSummary (control).
// The choice of display method is up to the architect; Repeaters and GridViews have many features you do not
// get with in-page script; there is however a performance tradeoff (~20% for this page); we opted to use
// in-page script vs. Repeaters/Gridviews here becuase the Quotes page is likely to be the most-often called
// page in the application; we did the same for the OrdersAltert control that is embedded in every authenticaterd
// display page. We utilize Repeaters elsehwhere. Note Trade 6.1 uses in-page JSP script in all pages.
