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 (@ref bcMaxEntries) as well as the time after which an entry is deleted (@ref bcDelTime).
If you prefere a memory-less version you should set to false the <verbatim>plainFlooding</verbatim> bool parameter.
