The Aura Signal package is a SignalSlots/EventHandler implementation for PHP. With it, we can invoke handlers ("slots" or "hooks") whenever an object sends a signal ("notification" or "event") to the signal manager.

This package is compliant with [PSR-0](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-0.md), [PSR-1](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-1-basic-coding-standard.md), and [PSR-2](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-2-coding-style-guide.md). If you notice compliance oversights, please send a patch via pull request.
