clang-check.sh

# -----------------------------------------------------------------------
# Useful script for invoking clang against Arduino source code to take
# advantage of clang's analysis tools.
# 
# Currently only works on OS X with an Xcode installation, but probably
# would work on Linux with some tweaking.
#
# Already picked up some errors:
