* Provides a means to interact with web servers. It is a near-complete implementation of the XMLHttpRequest API described in
* the Mozilla docs:
* <a href="https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest">https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest</a>.
*
* <p>Create using <code>new XMLHttpRequest(...)</code>.</p>
*
* @class XMLHttpRequest
*
* @hifi-interface
* @hifi-client-entity
* @hifi-avatar
* @hifi-server-entity
* @hifi-assignment-client
*
* @property {*} response - The response data.
* <em>Read-only.</em>
* @property {string} responseText - The response data as text.
* <em>Read-only.</em>
* @property {string} responseType - The response type required or received (e.g., <code>"text"</code>, <code>"json"</code>,
* <code>"arraybuffer"</code>, ...).
* @property {number} status - The <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Status">HTTP response status
* code</a> (<code>100</code> &ndash; <code>599</code>).
* <em>Read-only.</em>
* @property {string} statusText - The HTTP response status text.
* <em>Read-only.</em>
* @property {XMLHttpRequest.ReadyState} readyState - The status of the request.
* <em>Read-only.</em>
* @property {XMLHttpRequest.NetworkError} errorCode - The network result of the request: including, <code>0</code> (NoError)
* if there was no error, <code>4</code> (TimeoutError) if the request timed out.
* <em>Read-only.</em>
* @property {number} timeout - The time a request can take before timing out, in ms.
*
* @property {XMLHttpRequest.ReadyState} UNSENT - Request has been created; {@link XMLHttpRequest.open} not called yet.
* <em>Read-only.</em>
* @property {XMLHttpRequest.ReadyState} OPENED - {@link XMLHttpRequest.open} has been called.
* <em>Read-only.</em>
* @property {XMLHttpRequest.ReadyState} HEADERS_RECEIVED - {@link XMLHttpRequest.send} has been called; headers and status
* are available.
* <em>Read-only.</em>
* @property {XMLHttpRequest.ReadyState} LOADING - Downloading; {@link XMLHttpRequest|XMLHttpRequest.responseText} has partial
* data.
* <em>Read-only.</em>
* @property {XMLHttpRequest.ReadyState} DONE - Operation complete.
* <em>Read-only.</em>
*
* @property {XMLHttpRequest~onTimeoutCallback} ontimeout - Function called when the request times out.
* <p>Note: This is called in addition to any function set for <code>onreadystatechange</code>.</p>
* @property {XMLHttpRequest~onReadyStateChangeCallback} onreadystatechange - Function called when the request's ready state
* changes.
*
* @example <caption>Get a web page's HTML.</caption>
* var URL = "https://www.highfidelity.com/";
*
* var req = new XMLHttpRequest();
* req.onreadystatechange = function () {

*
* req = null;
