Simulating Network Latency In AngularJS With $http Interceptors And $timeout

Over the weekend, when I was exploring routing, caching, and nested views with ngRoute in AngularJS 1.x, I wanted to slow down the HTTP speed so that the user could experience Views in a "pending state." But, because I was working with my local system, HTTP requests were completing very quickly, in about 15ms. To get around this I used an HTTP interceptor to simulate network latency in a controlled fashion.
