Timer example

Timers are handy to notify program when some time interval expires.

Compilation

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

$ ./build.sh timer

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.
