helper script for control debug
tester script for avrora
node_host is ready to be tested in avrora
Returned back node_host serial port
Fixed node_host wrong data transmission

Debug output interferes with data payload
check_mrf in node_host
node_blinker is assembled on another arduino board
remove transmission timeout check
refactored py_teser code

device.py to access arduino device through serial port
avrora.py to access avrora simulation through socket
common.py - implementation of protocol test
fixed double answer to beacon
commented out all testing code, useful on avrora
tester supports other commands
