@ngdoc service
@name $exceptionHandler
@requires ng.$log
@this

@description
Any uncaught exception in AngularJS expressions is delegated to this service.
The default implementation simply delegates to `$log.error` which logs it into
the browser console.

In unit tests, if `angular-mocks.js` is loaded, this service is overridden by
{@link ngMock.$exceptionHandler mock $exceptionHandler} which aids in testing.

## Example:

The example below will overwrite the default `$exceptionHandler` in order to (a) log uncaught
errors to the backend for later inspection by the developers and (b) to use `$log.warn()` instead
of `$log.error()`.

```js
  angular.
    module('exceptionOverwrite', []).
    factory('$exceptionHandler', ['$log', 'logErrorsToBackend', function($log, logErrorsToBackend) {
      return function myExceptionHandler(exception, cause) {
        logErrorsToBackend(exception, cause);
        $log.warn(exception, cause);
      };
    }]);
```

<hr />
Note, that code executed in event-listeners (even those registered using jqLite's `on`/`bind`
methods) does not delegate exceptions to the {@link ng.$exceptionHandler $exceptionHandler}
(unless executed during a digest).

If you wish, you can manually delegate exceptions, e.g.
`try { ... } catch(e) { $exceptionHandler(e); }`

@param {Error} exception Exception associated with the error.
@param {string=} cause Optional information about the context in which
      the error was thrown.
