// JSONscriptRequest -- a simple class for making HTTP requests
// using dynamically generated script tags and JSON
//
// Author: Jason Levitt
// Date: December 7th, 2005
//
// A SECURITY WARNING FROM DOUGLAS CROCKFORD:
// "The dynamic <script> tag hack suffers from a problem. It allows a page 
// to access data from any server in the web, which is really useful. 
// Unfortunately, the data is returned in the form of a script. That script 
// can deliver the data, but it runs with the same authority as scripts on 
// the base page, so it is able to steal cookies or misuse the authorization 
// of the user with the server. A rogue script can do destructive things to 
// the relationship between the user and the base server."
//
// So, be extremely cautious in your use of this script.
//
//
// Sample Usage:
//
// <script type="text/javascript" src="jsr_class.js"></script>
// 
// function callbackfunc(jsonData) {
//      alert('Latitude = ' + jsonData.ResultSet.Result[0].Latitude + 
//            '  Longitude = ' + jsonData.ResultSet.Result[0].Longitude);
//      aObj.removeScriptTag();
// }
//
// request = 'http://api.local.yahoo.com/MapsService/V1/geocode?appid=YahooDemo&
//            output=json&callback=callbackfunc&location=78704';
// aObj = new JSONscriptRequest(request);
// aObj.buildScriptTag();
// aObj.addScriptTag();
//
//
