+ Receives from the hardware serial, sends to software serial.
+ Receives from software serial, sends to hardware serial.
+ 
+ The circuit: 
+ * RX is digital pin 2 (connect to TX of other device)
+ * TX is digital pin 3 (connect to RX of other device)

+ created back in the mists of time
+ modified 9 Apr 2012
+ by Tom Igoe
+ based on Mikal Hart's example
+ 
+ This example code is in the public domain.
+ 
+ <SoftSerial> adapted from <SoftwareSerial> for <TinyPinChange> library which allows sharing the Pin Change Interrupt Vector.
+ Single difference with <SoftwareSerial>: add #include <TinyPinChange.h>  at the top of your sketch.
