'** This class makes it easy to create a button that can be appended

'** Dim rtbutton As New RichTextButton
'** Call rtbutton.SetLabel("Formula Button")
'** Call rtbutton.SetButtonLanguage(RTB_FORMULA)
'** Call rtbutton.SetCode( |@Prompt([ok]; "My Button"; "You clicked my button");| )
'** Set rtitem = doc.GetFirstItem("Body")
'** Call rtbutton.AppendButton(rtitem)
