Add additional "DataItemLevelIndex" and "DataItemLevelCount" attributes to Hierarchical Viewers/Transformations
When using Hierarchical Transformations we need to know how many items are in the current level being transformed as well as the current items index on that level. We can this already in repeater transformations with the DataItemIndex and DataItemCount attributes, but these don't help when you are using a hierarchical transformation because they just tell you how many items are being transformed in the whole dataset, not in relation to the current level.

thanks for the great suggestion. Unfortunately, it is not aligned with our current strategy and vision regarding Portal engine vs MVC.
