libmsgbuff
Tiny library to encapsulare messages on memory buffers.
This code is needed by the CAENRFID C libraries in order to get access to its RFID UHF readers, expecially for the Cosino Mega 2560 - UHF RFID KIT (http://www.cosino.io/product/cosino-mega-2560-uhf-rfid-kit).
Note that the following code is the unofficial version of the CAENRFID's code so don't waste the CAENRFID's guys on questions about what you're reading here!
