*Summary*
--------
+ <comphelper/flagguard.hxx> 
+ class FlagRestorationGuard

*Description*
-------------
FlagRestorartionGuard is a specialization of ::comphelper::ScopeGuard,
encapsulating the often-seen pattern of setting a certain boolean flag
to some value, and ensuring that it is reset to its previous value
upon leaving the current scope.
  {
    FlagRestorationGuard aGuard( bSomeFlag, true );
    ...
  } // bSomeFlag will be reset to the value it had at the beginning of
the scope
