Any uncaught exception in angular 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 mock $exceptionHandler which aids in testing.

## Example:

    angular.module('exceptionOverride', []).factory('$exceptionHandler', function () {
      return function (exception, cause) {
        exception.message += ' (caused by "' + cause + '")';
        throw exception;
      };
    });

This example will override the normal action of `$exceptionHandler`, to make angular exceptions fail hard when they happen, instead of just logging to the console.

## Dependencies

- `$log`

## Usage

`$exceptionHandler(exception, [cause]);`

### Arguments

Param | Type | Details
