MessagePack encoding for Golang

Supports:

• Primitives, arrays, maps, structs, time.Time and interface{}.
• Appengine *datastore.Key and datastore.Cursor.
• CustomEncoder/CustomDecoder interfaces for custom encoding.
• Extensions to encode type information.
• Renaming fields via msgpack:"my_field_name".
• Omitting individual empty fields via msgpack:",omitempty" tag or all empty fields in a struct.
• Map keys sorting.
• Encoding/decoding all structs as arrays or individual structs.
• Encoder.UseJSONTag with Decoder.UseJSONTag can turn msgpack into drop-in replacement for JSON.
• Simple but very fast and efficient queries.
