*
* When debug < 1 a CakeException will render 404 or 500 errors. If an uncaught exception is thrown
* and it is a type that ErrorHandler does not know about it will be treated as a 500 error.

* errors will be logged to CakeLog. You can control which errors are logged by setting
* `Error.level` in your core.php.
*
* #### Logging errors
*
* When ErrorHandler is used for handling errors, you can enable error logging by setting `Error.log` to true.
* This will log all errors to the configured log handlers.
*
* #### Controlling what errors are logged/displayed
*
* You can control which errors are logged / displayed by ErrorHandler by setting `Error.level`. Setting this
* to one or a combination of a few of the E_* constants will only enable the specified errors.
*
* e.g. `Configure::write('Error.level', E_ALL & ~E_NOTICE);`
*
* Would enable handling for all non Notice errors.

* ### Implementing application specific exception handling
* ### Implementing application specific exception rendering
*
* You can implement application specific exception handling in one of a few ways:
*
* - Create a AppController::appError();
* - Create an AppError class.
* - Create a subclass of ExceptionRenderer and configure it to be the `Exception.renderer`
*
* #### Using AppController::appError();
*
* This controller method is called instead of the default exception handling. It receives the
* thrown exception as its only argument. You should implement your error handling in that method.
*
* #### Using an AppError class
* #### Using a subclass of ExceptionRenderer
*
* This approach gives more flexibility and power in how you handle exceptions. You can create
* `app/libs/app_error.php` and create a class called `AppError`. The core ErrorHandler class
* will attempt to construct this class and let it handle the exception. This provides a more
* flexible way to handle exceptions in your application.
* Using a subclass of ExceptionRenderer gives you full control over how Exceptions are rendered, you
* can configure your class in your core.php, with `Configure::write('Exception.renderer', 'MyClass');`
* You should place any custom exception renderers in `app/libs`.
