Time formatting example

This is just silly example to fiddle with numbers and timestamps.

Compilation

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

$ ./build.sh time_format

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.
