 A package of golang structs for reading/modifying MongoDB replset config and state. The structs are to unmarshal the output of the ['replSetGetConfig'](https://docs.mongodb.com/manual/reference/command/replSetGetConfig/) and ['replSetGetStatus'](https://docs.mongodb.com/manual/reference/command/replSetGetStatus/) server commands
