April 12 2013 // V1.0 based on panstamp library V14 and panstamp sketches v24
---------------
-panstamp.cpp : modified to handle packets outside of interrupts ISRGD0
-config.h : REPEATER_TABLE_DEPTH modified to 2 to limit RAM consumption as repeater is not used in panMillenium
-REGS.h/cpp : new file added to introduce a new registers construction mechanism
-modbusBasic.h/cpp : contains a basic modbus implementation compatible with Crouzet Millenium 


 need the library folder modbusBasic
examples :
- panMillenium3 : application for exchanging registers SLin/SLout over the panstamp/swap network.  
  NEED SCoop.h library
  NEED IOFilter.h library
  
- modemMillenium : new modem application, compatible with original panstamp/swap application, adding new AT commands


Mar 20 2013
---------------
 - Fixed problem with Timer 2 being disabled during SLEEP

Feb 23 2013
---------------
 - Self-detection of 32.768 KHz crystal
 - Timer 1 reverted to its original settings after calibration

Feb 10 2013
---------------
- Fixed problem about Rx interrupts happening wjilst in Tx mode
- Señf-detection of the external 32.768 KHz crystal. No more need to define (or comment)
EXTERNAL_RTC_CRYSTAL in config.h

Jan 17 2013
---------------
- Check for RX_OVERFLOW in sendData whilst trying to enter Rx state

Dec 10 2012
---------------
- EXTERNAL_RTC_CRYSTAL now enabled by default from config.h. This option needs to be disabled
for old versions of panStamp, without the external 32.768 KHz crystal
