/**
A wrapper of I18N wrappers. Using this is more expensive than using some
single wrapper classes so use it only if you must pass a single pointer
without knowing in advance what is needed, e.g. for
SfxPoolItem::GetPresentation(). Remember that this wrapper was only created
for convenience to bypass some oddities, if possible don't use it. <p>
Implemented are only the const get...() methods of the wrappers, which are
loaded on demand, for consistency reasons no change of locale is possible.
Only default calendar and default collator are supported. <p>
One exception though is the calendar wrapper: to be able to set a value and
retrieve calendar values it is not const, so methods using this should
reset the calendar to the previous value if it isn't sure where the
IntlWrapper did come from. <p>
