Obsolete class, only kept for backwards compatibility. The type classes TypeReal, TypeInteger etc. have been introduced to associate an icon to the built-in base classes Real, Integer etc. Instead for Complex, an icon is already introduced in its definition (which is not possible for the built-in classes). Therefore, TypeComplex is just an alias to Complex and is therefore superfluous.
