\class EditToolBar
\brief A ToolBar that has the edit buttons on it.

  This class, which is a child of Toolbar, creates the
  window containing interfaces to commonly-used edit
  functions that are otherwise only available through
  menus. The window can be embedded within a normal project
  window, or within a ToolbarFrame that is managed by a
  global ToolBarStub called gControlToolBarStub.

  All of the controls in this window were custom-written for
  Audacity - they are not native controls on any platform -
  however, it is intended that the images could be easily
  replaced to allow "skinning" or just customization to
  match the look and feel of each platform.
