Node and user info example

This example fetches some info about underlying machine and user who started this program.

Compilation

Easiest way to get this example running is to go to examples directory in package root, and run:

$ ./build.sh node_info

build.sh script compiles Ano script to C, copies source files in place and pops up instructions what to do next. Follow them. Check also examples/README for more info.
