+/**
+ * Functionality of this auto ptr class is same as stl's auto_ptr class
+ * except this works with cleanup stack.
+ * Implementation of the example operation with "traditional" way:
+ * void bar()
+ *   {
+ *   CFoo* myFoo = CFoo::NewL();
+ *   CleanupStack::PushL(myFoo);
+ *   myFoo->DoSomeThingL();
+ *   CleanupStack::PopAndDestroy(1); //myFoo
+ *   }
+ * Implementation of the same function with auto pointer class:
+ * void bar()
+ *   {
+ *   jcfcommon::auto_ptr<CFoo> myFoo(CFoo::NewL());
+ *   myFoo->DoSomeThingL();
+ *   }
+ *
