0.7.0

Support context for MarshalJSON and UnmarshalJSON ( #248 )

• json.MarshalContext(context.Context, interface{}, ...json.EncodeOption) ([]byte, error)
• json.NewEncoder(io.Writer).EncodeContext(context.Context, interface{}, ...json.EncodeOption) error
• json.UnmarshalContext(context.Context, []byte, interface{}, ...json.DecodeOption) error
• json.NewDecoder(io.Reader).DecodeContext(context.Context, interface{}) error

type MarshalerContext interface {
  MarshalJSON(context.Context) ([]byte, error)
}

type UnmarshalerContext interface {
  UnmarshalJSON(context.Context, []byte) error
}

Add DecodeFieldPriorityFirstWin option ( #242 )

In the default behavior, go-json, like encoding/json, will reflect the result of the last evaluation when a field with the same name exists. I've added new options to allow you to change this behavior. json.DecodeFieldPriorityFirstWin option reflects the result of the first evaluation if a field with the same name exists. This behavior has a performance advantage as it allows the subsequent strings to be skipped if all fields have been evaluated.
