<div class="block">Wraps mock implementations of API interfaces so that they exhibit the delay and error
 characteristics of a real network.
 <p>
 Because APIs are defined as interfaces, versions of the API that use mock data can be created by
 simply implementing the API interface on a class. These mock implementations execute
 synchronously which is a large deviation from the behavior of those backed by an API call over
 the network. By wrapping the mock instances using this
