##EsriHttpClient: Get the Current signed on User

//Reference Newtonsoft - Json.Net
  //Reference System.Net.Http

// an anonymous request against the portal

//Assume that you have executed the "Get the Current signed on User" snippet and have 'userName'

##EsriHttpClient: Get a Service Layer and Add it to Pro
