// CSTabCtrl window
//
// Implements a tab control that automatically handles the showing and hiding
// of objects attached to a tab's various pages eliminating the need to do so
// via the ON_NOTIFY(TCN_SELCHANGE... ) message.
//
// 1.	Simply replace any instance of a CTabCtrl with CSTabCtrl,
//		initialize it as you would an MFC CTabCtrl.
// 2.	Use the AttachControlToTab member to attach you objects 
//		to the various avaliable pages.
// 
// 3.	(optional) Use the SetCurSel member to programaticly show
//		a tabs particular page.
//
// Once done the tab control will show and hide the attached objects depending
// on the users tab selection.

// example of CSTabCtrl's use.
