//
// A simple flooding protocol for network-level broadcast.
//
// This implementation uses plain flooding, i.e. it "remembers"
// (stores) already broadcasted messages in a list and does not
// rebroadcast them again if it gets another copy of that message.
//
// The maximum number of entries for that list can be defined in the
// .ini file (`bcMaxEntries` parameter) as well as the time after which an entry
// is deleted (`bcDelTime` parameter).
//
// If you prefer a memory-less version, you should set the `plainFlooding` bool parameter to false.
