/**************************************************************************/
/*!
@file Adafruit_PN532.h
v2.0 - Refactored to add I2C support from Adafruit_NFCShield_I2C library.
v1.1 - Added full command list
- Added 'verbose' mode flag to constructor to toggle debug output
- Changed readPassiveTargetID() to return variable length values
