How this all works is to dynamically register a html script element to the <head> tag of the page via acessing the DOM. Within this script is contained the call to the translator ajax service api, as well as a callback function. Once the AJAX call to the Microsoft Translator API is complete, the API will return to the callback handler function that we have previously nominated.';
