-// Encode writes an object into a stream.
-//
-// Encoding can be configured via the struct tag for the fields.
-// The "codec" key in struct field's tag value is the key name,
-// followed by an optional comma and options.
-// Note that the "json" key is used in the absence of the "codec" key.
-//
-// To set an option on all fields (e.g. omitempty on all fields), you
-// can create a field called _struct, and set flags on it.
-//
-// Struct values "usually" encode as maps. Each exported struct field is encoded unless:
-//    - the field's tag is "-", OR
-//    - the field is empty (empty or the zero value) and its tag specifies the "omitempty" option.
-//
-// When encoding as a map, the first string in the tag (before the comma)
-// is the map key string to use when encoding.
-//
-// However, struct values may encode as arrays. This happens when:
-//    - StructToArray Encode option is set, OR
-//    - the tag on the _struct field sets the "toarray" option
-//
-// Values with types that implement MapBySlice are encoded as stream maps.
-//
-// The empty values (for omitempty option) are false, 0, any nil pointer
-// or interface value, and any array, slice, map, or string of length zero.
-//
-// Anonymous fields are encoded inline except:
-//    - the struct tag specifies a replacement name (first value)
-//    - the field is of an interface type
-//
-// Examples:
-//
-//      // NOTE: 'json:' can be used as struct tag key, in place 'codec:' below.
-//      type MyStruct struct {
-//          _struct bool    `codec:",omitempty"`   //set omitempty for every field
-//          Field1 string   `codec:"-"`            //skip this field
-//          Field2 int      `codec:"myName"`       //Use key "myName" in encode stream
-//          Field3 int32    `codec:",omitempty"`   //use key "Field3". Omit if empty.
-//          Field4 bool     `codec:"f4,omitempty"` //use key "f4". Omit if empty.
-//          io.Reader                              //use key "Reader".
-//          MyStruct        `codec:"my1"           //use key "my1".
-//          MyStruct                               //inline it
-//          ...
-//      }
-//
-//      type MyStruct struct {
-//          _struct bool    `codec:",omitempty,toarray"`   //set omitempty for every field
-//                                                         //and encode struct as an array
-//      }
-//
-// The mode of encoding is based on the type of the value. When a value is seen:
-//   - If a Selfer, call its CodecEncodeSelf method
-//   - If an extension is registered for it, call that extension function
-//   - If it implements encoding.(Binary|Text|JSON)Marshaler, call its Marshal(Binary|Text|JSON) method
-//   - Else encode it based on its reflect.Kind
-//
-// Note that struct field names and keys in map[string]XXX will be treated as symbols.

-// only once in the stream, and use a tag to refer to it thereafter.
