// List operations support negative indexing.  If the index is negative, the
// resolved index starts backwards from end of list. If an index is out of bounds,
// a parameter error will be returned. If a range is partially out of bounds, the
// valid part of the range will be returned. Index/Range examples:
//
// Index/Range examples:
//
//    Index 0: First item in list.
//    Index 4: Fifth item in list.
//    Index -1: Last item in list.
//    Index -3: Third to last item in list.
//    Index 1 Count 2: Second and third items in list.
//    Index -3 Count 3: Last three items in list.
//    Index -5 Count 4: Range between fifth to last item to second to last item inclusive.
//
// Nested CDT operations are supported by optional Ctx context arguments.  Examples:
//
// bin = [[7,9,5],[1,2,3],[6,5,4,1]]
// Append 11 to last list.
// ListAppendWithPolicyContextOp(DefaultMapPolicy(), "bin", IntegerValue(11), CtxListIndex(-1))
// bin result = [[7,9,5],[1,2,3],[6,5,4,1,11]]
//
// bin = {key1:[[7,9,5],[13]], key2:[[9],[2,4],[6,1,9]], key3:[[6,5]]}
// Append 11 to lowest ranked list in map identified by "key2".
// ListAppendWithPolicyContextOp(DefaultMapPolicy(), "bin", IntegerValue(11), CtxMapKey(StringValue("key2")), CtxListRank(0))
// bin result = {key1:[[7,9,5],[13]], key2:[[9],[2,4,11],[6,1,9]], key3:[[6,5]]}
