Just a quick note to some people who've provided help, suggestions,
bug-fixes, etc. along the way...

Nick Lott: (And others)
Hints about making it work with C++

Philipp Stefan Neininger:
Minor bug in the Makefile to do with cross compiling

Chris McSweeny
Hints and tips about the use of arithmetic in gettimeofday()
inside the dealyMicrosecondsHard() function.
And spotting a couple of schoolboy errors in the (experimental)
softServo code, prompting me to completely re-write it.

Armin (Via projects website)
Some pointers about the i2c-dev.h files.

Arno Wagner
Suggestions for the mmap calls in wiringPiSetup()

CHARLES Thibaut:
A small issue in softTone

Xian Stannard
Fixing some typos in the man page!

Andre Crone
Suggested the __WIRING_PI.H__ round wiringPi.h

Rik Teerling
Pointing out some silly mistooks in the I2C code...
