-    @section  HISTORY
-    
-    v2.1 - Added NTAG2xx helper functions
-
-    v2.0 - Refactored to add I2C support from Adafruit_NFCShield_I2C library.
-
-    v1.4 - Added setPassiveActivationRetries()
-
-    v1.2 - Added writeGPIO()
-         - Added readGPIO()
-
-    v1.1 - Changed readPassiveTargetID() to handle multiple UID sizes
-         - Added the following helper functions for text display
-             static void PrintHex(const byte * data, const uint32_t numBytes)
-             static void PrintHexChar(const byte * pbtData, const uint32_t
-   numBytes)
-         - Added the following Mifare Classic functions:
-             bool mifareclassic_IsFirstBlock (uint32_t uiBlock)
-             bool mifareclassic_IsTrailerBlock (uint32_t uiBlock)
-             uint8_t mifareclassic_AuthenticateBlock (uint8_t * uid, uint8_t
-   uidLen, uint32_t blockNumber, uint8_t keyNumber, uint8_t * keyData) uint8_t
-   mifareclassic_ReadDataBlock (uint8_t blockNumber, uint8_t * data) uint8_t
-   mifareclassic_WriteDataBlock (uint8_t blockNumber, uint8_t * data)
-         - Added the following Mifare Ultalight functions:
