			//
			//	This is a user control (probably named MM:DataSet or something like that).
			//	It has been instantiated on an ASPX page.  This user control has an inner
			//	tag called Parameters.	That corresponds to the property of this user
			//	control's class that has been named _params.  It is an ArrayList.  So
			//	_params is a child of this user control.  Within the Parameters tag can live
			//	one or more Parameter tags (note the lack of the s at the end).  Each
			//	Parameter tag is an HtmlGenericControl.  They get created by the ASPX page
			//	under the hood (when that page is turned into C# or VB, etc., before the
			//	.Net system compiles and links it into a DLL).	So each HtmlGenericControl
			//	is a child of the ArrayList.
			//
			//	When a page or control calls DataBind it has to have a binding container.
			//	But a binding container is only assigned to objects that have as a parent a
			//	page or control.
			//
			//	Note that the HtmlGenericControl is a child of an ArrayList, not a page or
			//	control.  Therefore, calling DataBind on it will cause an exception to be
			//	thrown.
			//
			//	We have to make a dual-parentage for these HtmlGenericControl instances.
			//	They have to be parented to a control or page.	It turns out that .Net does
			//	allow a control to parent itself to its page's controls.  So we will do
			//	the next best thing.  We'll parent the HtmlGenericControl it the user
			//	control.  It's kind of like skipping a level (because we are skipping the
			//	ArrayList).  But that's not entirely accurate because the ArrayList remains
			//	a parent of the HtmlGenericControl in the sence that it has been added to
			//	that array.  That doesn't change.  We are really just making a NEW
			//	parentage to the user control, too.
			//
			//	Note that we add the control, bind it and then immediately remove it.  The
			//	removal is needed to prevent the system from writing out this control onto
			//	the response.  We don't want <PARAMETER ...></PARAMETER> actually showing up
			//	in the HTML passed down to the browser.  If we don't do the remove, that is
			//	exactly what happens.  This would reveal a server-side control to the browser

//  FieldValueAtIndex
//
//  PURPOSE:  This function determines the value of a named field within some row within
//		this DataSet.  The tricky part is determining which row is desired.  Consider an
//		example.  Suppose we have a page containing 3 DataSets:  ds1, ds2 and ds3.  This
//		page might contain a DataGrid, g1, bound to ds1.  Within the DataGrid may be
//		with a TemplateColumn containing a Repeater, r1, bound to ds2.  Within the Repeater
//		might be an ItemTemplate containing ds1.FieldValue("foo", Container) as well as
//		ds2.FieldValue("bar", Container).  Outside the whole DataGrid might be another
//		Repeater, r2, bound to ds1 containing an ItemTemplate containing
//		ds1.FieldValue("foo", Container) and ds3.FieldValue("xyz", Container).  We can
//		diagram this as:
//
//		DataSet ds1
//		DataSet ds2
//		DataSet ds3
//
//		DataGrid g1 bound to ds1
//			TemplateColumn
//				ItemTemplate
//					Repeater r1 bound to ds2
//						ItemTemplate
//							ds1.FieldValue("foo", Container)  [use the row in ds1 that g1 is currently processing]
//							ds2.FieldValue("bar", Container)  [use the row in ds2 that r1 is currrently processing]
//
//		Repeater r2 bound to ds1
//			ds1.FieldValue("foo", Container) [use the row in ds1 that r2 is currently processing]
//			ds3.FieldValue("xyz", Container) [use the 0th row in ds3]
//		
//		The challenge presented to this method is to resolve the field values according to the
