* Example RF Radio Ping Pair which Sleeps between Sends

*
|

* This is an example of how to use the RF24 class to create a battery-
|

* efficient system. It is just like the pingpair.pde example, but the
|
||||
* ping node powers down the radio and sleeps the MCU after every
|

* ping/pong cycle.
|
||||
*
|

* As with the pingpair.pde example, write this sketch to two different nodes,
|
||||
* connect the role_pin to ground on one. The ping node sends the current
|
||||
* time to the pong node, which responds by sending the value back. The ping
|
||||
* node can then see how long the whole cycle took.
