+// When a class must encapsulate a collection of references (offsets) to other 
+// objects, this is represented as 1-element arrays.
+//
+// From the class' point of view there is only a single element in the array.
+// In reality, there will be more or less than one element, depending on the value of 
+// TTzWhatever::iNumberOfWhateverElements. The actual offsets will be persisted IMMEDIATELY
+// AFTER the class, thus becoming an extension of the array. We can then get the i-th
+// element by doing TTzWhatever::iOffsetsToWhateverElements[i].
