Hello World
Helloworld program.
Set up third party library build and a few demos.
Add 4 third party libraries: gflags, glog, libunwind, gtest.
third_party/libunwind-1.1 was not complete in the last commit since there was an .gitignore that came with the library.
Forgot to create lib/ and bin/ directory. Fixed now.
Add zmq-3.2.3 and rename .cc to .cpp and .h to .hpp in third_party_demo.
Disable building doc in libunwind to avoid calling latex2man, which the user might not have without installing latex.
fix zmq.hpp
The zeromq demo (hwclient and hwserver) are working now.
modified directory structure
corrected gtest.mk
