Before we go any further, I want to point out that the more complex classes of the

RFM22 module- RF22Datagram, RF22ReliableDatagram, RF22Router and

RF22Mesh- are known to run poorly or not at all on ATmega328P based Arduino-

compatibles (UNO, Pro, ProMicro, Duemilanova, etc) and none of the RF22 library

support works on ATmega168 based boards (although those are only the very oldest

of boards). At the time of this writing, support for Leonardo and other 32u4 based

Arduino-compatibles (e.g., SparkFun's Promicro boards) has not been verified.

Support is in place for Arduino Mega boards, however.

Okay, now that I've gotten that warning out of the way, let's go ahead and load up

"rf22_client" and see what happens.
