+Test sketch for Sparkfun's RFID Evaluation Shield - 13.56MHz (https://www.sparkfun.com/products/10406).
+
+Minor modifications to Aaron Weiss's original code (http://dlnmh9ip6v2uc.cloudfront.net/datasheets/Sensors/ID/RFID_Eval_13_56MHz_v10.pde) to enable compatibility with Arduino 1.0 which now incorporates an implementation of NewSoftSerial.

+/*
+  RFID Eval 13.56MHz Shield example sketch v10
+
+  Aaron Weiss, aaron at sparkfun dot com
+  OSHW license: http://freedomdefined.org/OSHW
+
+  works with 13.56MHz MiFare 1k tags
+
+  Based on hardware v13:
+  D7 -> RFID RX
+  D8 -> RFID TX
+  D9 -> XBee TX
+  D10 -> XBee RX
+
+  Note: RFID Reset attached to D13 (aka status LED)
+
+  Note: be sure include the SoftwareSerial lib, http://arduiniana.org/libraries/newsoftserial/
+
+  Usage: Sketch prints 'Start' and waits for a tag. When a tag is in range, the shield reads the tag,
+  blinks the 'Found' LED and prints the serial number of the tag to the serial port
+  and the XBee port.
+  
+  06/04/2013 - Modified for compatibility with Arudino 1.0. Seb Madgwick.
