+ *                which are used all over Symbian's CalenInterimAPI.
+ *                Implementation is more or less copy-paste of
+ *                cleanup item of Close method and CleanupClosePushL

+/**
+ *  Constructs and pushes a TCleanupItem object onto the cleanup stack.
+ *  
+ *  The TCleanupItem encapsulates:
+ *
+ *  1. a reference aRef to the object of type class T which is to be cleaned up
+ *  2. an associated cleanup operation.
+ *  
+ *  The cleanup operation is the private static function ResetAndDestroy() of 
+ *  the templated class CleanupResetAndDestroy and is invoked as a result of 
+ *  a subsequent call to CleanupStack::PopAndDestroy().
+ *  
+ *  CleanupResetAndDestroy::ResetAndDestroy() is passed a pointer to the 
+ *  class T object to be cleaned up, and the function implements cleanup by 
+ *  calling ResetAndDestroy() on the passed object.
+ *  The class T object must, therefore, define and implement (or inherit) a 
+ *  ResetAndDestroy() member function.
+ *
+ *  RPointerArray<HBufC> buffers;
+ *  CleanupResetAndDestroyPushL( buffers );
+ *  buffers.Append( HBufC::NewL(100) );
+ *  ...
+ *  CleanupStack::PopAndDestroy(); // <--- results in ResetAndDestroy() being called on "buffers".
+ *  ...
+ *  @endcode
+ *  
+ *  @param aRef A reference to a class T type object for which the cleanup item is being created.
