Moving examples under nanpy/examples to make examples part of the distribution
if instead of ifdef for FreqCounter
Removed useless code, do not track cfg.h
Better firmware configuration
Added Tone class
Restored includes, fixes #20
put Tone under namespace
put Tone inside #if #endif
rename Tone to ToneWrapper

Strange behavior:
Tone.cpp file makes Arduino link tone() function,
which conflicts Counter.
new RAM.free() function
eeprom example: 16 bytes in one line, remove spaces
cache portOutputRegister, portInputRegister, portModeRegister return values
use object based interface in more examples
use object based interface in README
enable some modules in sample cfg.h
default BOARD is uno in makefile
move watchdog related code into WatchdogClass.cpp
Added Anthony Goodhew to contributors
Fixed watch dog disable at startup issue
Separate makefile stuff
