Detailed Description

This class represent and very simple way to trap and handle hang-up signals. It is not and never was intended to be a fully fledged signal handling framework. It's only job in life is to allow you to register a handler (which can be a simple free standing function or a functor), which will be called if the posix standard SIGHUP signal is raised.

The default behaviour that a process should implement is to reload the configuration file and then use any changes found.

To use it just call it from an appropirate place in your main thread before you start any services or actions that might need clearing up on termination. It is up to you to ensure your custom handler shuts down your process. The normal action of termination will be disabled.
