    [[Text Formatter API to manage text formatting(attributes).
     Use it to insert and remove style attributes (font, size, color, ...) using @Efl.Text.Cursor on EFL Widgets.

     Attributes can be assigned to character ranges, selected using two @Efl.Text.Cursor instances.
     Cursor instances are already bound to a text object so there's no need to provide it to this class.
     Style is specified using format strings as described in @Efl.Canvas.Textblock.style_apply.

     There is no need to instantiate this class. Use directly the @.attribute_insert and @.attribute_clear static methods.
