 /** Provides a templated stack that allows items in the stack to be marked.

 The class allows each mark to have an associated TInt value, which allows different 

 types of mark to be used on the same stack.

 Template parameter T specifies the type of object on the stack. Owner should be set to 

 ETrue if the object's destructor should delete the objects on the stack.
