Mixin class template for deriving new interface declarations.
mi::base::Interface_declare is a mixin class template that allows you to derive new interface classes easily. It provides you with implementations for the interface ID handling and support for the mi::base::IInterface::get_interface method used by the corresponding mixin class template mi::base::Interface_implement.
It derives from the interface I, which is by default mi::base::IInterface. Each interface needs an interface ID (represented as a universally unique identifier (UUID)), which is defined here as 11 template parameter constants.
