Change operator[] for getRef(..) method, so instead of returning a pointer, return a reference to ParaPortion instead. This also needs changes to the code, because we now need to make sure before hand that the ParaPortion is really available in the list and when this is not possible or convenient, the change the call to use existing "SafeGetObject" instead. Add "exists" to check if the object is available in the ParaPortionList. In addition add "lastIndex" method to return the index of the last ParaPortion in the list (shortcut for Count() - 1).
