Indexer support in binding paths

[jefffhaynes]

It would be nice if path syntax supported indexers for collection binding

Can you also add a range like expression for bindings, because there's a lot of cases where there's 2 arrays/lists in which one contains the offset and the other contains the actual data so it would help to have something like FieldOffset("OffsetList", IterateType.All) and it will use the value in the list at the index of the current item
