Detailed Description

System signal manager.

This class dispatches signals received from the system to the appropriate handlers or sets a signal to be ignored. This class is never instantiated but rather you just register a handler. After you are done with signal handling call finalize() to free the use resources and de-register all signal handlers at once.
