//----------------------------------------------------------------------------
// Class:   RtrPropertySheet
//
// This class is used by property sheets in the router administration tool.
// It is intended to host pages derived from RtrPropertyPage (below).
//
// This is derived from CPropertyPageHolderBase.  Sheets derived
// from this class allow their creators to specify a callback
// to be invoked when certain events occur, such as closing the sheet or
// applying changes.
// 
// It also allows its contained pages to accumulate their changes in memory
// when the user selects "Apply"; the changes are then saved together,
// rather than having each page save its own changes.
// Note that this increases the performance of the router UI, which uses RPC
// to save its information; using this class results in a single RPC call
// to save changes, rather than separate calls from each of the pages.

// Class:   RtrPropertyPage
//
// This class is used for property-pages in the router administration tool.
// It is intended to be contained by a RtrPropertySheet-derived object.
//
// This class supports the ability for the RtrPropertySheet to do
// the actual apply (to save on RPCs we batch the Apply into one function
// at the sheet level rather than the page level).  The page does
// this by setting the sheet to be dirty when the page itself is marked
// dirty.  The actual code to save the global data in the PropertySheet
// is done by the RtrPropertySheet.
//
// When an apply is performed, the RtrPropertySheet calls "ApplySheetData"
// on each of the pages.  The pages will then save their data and the
// property sheet will then save this global data.
