Re-writing Adafruit's AF_XPort library for Arduino IDE 1.0

Oh, I was trying to refer to myself. I'm a Java programmer by day, and didn't realize C++ used that other syntax. I'm guessing that's to initialize a member object from within a constructor? Anyway, I assumed the syntax would be the same as the SoftwareSerial example, which looked similar enough to Java. I had a hard enough time not writing "new"!
