Should Ardent have a TypeException?

[Wes0617]

I would throw an EngineException (PHP7) for consistency with PHP's own type hinting.
Or, better, I'd use trigger_error() for PHP5 compatibility (which would presumably result in a EngineException in PHP7)

PHP 7 is likely adding a TypeException class. I'll wait to see how that all pans out.

As an update PHP 7 will have TypeError which does not descend from \Exception but is a sibling class instead. I will need to re-evaluate what I do in this repository for all exceptions because of this.
