## Description

Intercepts all `$http` requests that return with an error. It will then broadcast the event `httpInterceptorError`
which will provide the error object containing the status code, status text and other error information.

### Usage

```js wrap  theme={"dark"}
angular
module('myApp', ['lightning'] )
.* .run(['$rootScope', '$templateCache','$location','$timeout', function ($rootScope, $templateCache, $location,$timeout) {
$rootScope.$on('httpInterceptorError', function(event,error) {
    //File not found is HTML
    if(error.config.headers.Accept == 'text/html'){
        if(error.status == '404'){
            alert('Page Not Found!');
            //Timeout is required to redirect the page after all other events have fired
            $timeout(function(){
                $location.path('search');
            },0)
        }
    }
});
```
