Error handling + Custom 404 and 500 pages at PIMF

All of the configuration options regarding errors and logging live in the config.php file.

/*
|------------------------------------------------------------------------
| Settings for the error handling behavior
|------------------------------------------------------------------------
*/
'error' => array(
  'ignore_levels' => array(E_USER_DEPRECATED),
  'debug_info' => true,
  'log' => true,
),

The 'ignore_levels' option contains an array of error levels that should be ignored by PIMF. By "ignored", we mean that we won't stop execution
of the script on these errors. However, they will be logged when logging is enabled.

The 'debuginfo' option indicates if the framework should display the error message and stack trace when an error occurs. For development, you
will want this to be 'true'. In a production environment, set this to 'false'. When 'debuginfo' is disabled, the view located in 'core/Pimf/_error/500.php' will be displayed, which contains a generic error message.

To enable logging, set the 'log' option in the error configuration to 'true'. When enabled, the Closure defined by the logger configuration
item will be executed when an error occurs. This gives you total flexibility in how the error should be logged.

Custom 404 and 500 pages

If you want to customize the the 404 or 500 view, just override it by creating a clone of it at you application like 'app/MyFirstBlog/_error/500.php'.
