// Unique key map bin operations. Create map operations used by the client operate command.
// The default unique key map is unordered.
//
// All maps maintain an index and a rank.  The index is the item offset from the start of the map,
// for both unordered and ordered maps.  The rank is the sorted index of the value component.
// Map supports negative indexing for index and rank.
//
// Index examples:
//
//  Index 0: First item in map.
//  Index 4: Fifth item in map.
//  Index -1: Last item in map.
//  Index -3: Third to last item in map.
//  Index 1 Count 2: Second and third items in map.
//  Index -3 Count 3: Last three items in map.
//  Index -5 Count 4: Range between fifth to last item to second to last item inclusive.
//
//
// Rank examples:
//
//  Rank 0: Item with lowest value rank in map.
//  Rank 4: Fifth lowest ranked item in map.
//  Rank -1: Item with highest ranked value in map.
//  Rank -3: Item with third highest ranked value in map.
//  Rank 1 Count 2: Second and third lowest ranked items in map.
//  Rank -3 Count 3: Top three ranked items in map.
//
//
// Nested CDT operations are supported by optional CTX context arguments.  Examples:
//
//  bin = {key1:{key11:9,key12:4}, key2:{key21:3,key22:5}}
//  Set map value to 11 for map key "key21" inside of map key "key2".
//  MapOperation.put(MapPolicy.Default, "bin", StringValue("key21"), IntegerValue(11), CtxMapKey(StringValue("key2")))
//  bin result = {key1:{key11:9,key12:4},key2:{key21:11,key22:5}}
//
//  bin : {key1:{key11:{key111:1},key12:{key121:5}}, key2:{key21:{"key211":7}}}
//  Set map value to 11 in map key "key121" for highest ranked map ("key12") inside of map key "key1".
//  MapPutOp(DefaultMapPolicy(), "bin", StringValue("key121"), IntegerValue(11), CtxMapKey(StringValue("key1")), CtxMapRank(-1))
//  bin result = {key1:{key11:{key111:1},key12:{key121:11}}, key2:{key21:{"key211":7}}}
