used to initialize the component when instantiating.
In the ::com::sun::star::lang::XInitialization::initialize method, you can
pass a ::com::sun::star::lang::Locale to specify the default locale of the
number formats supplier.
The component should be initialized only once, after it has been instantiated, and before it
has been used.
If you initialize it a second time (or after you used it), it is up to implementation
how this is handled.
