 *
 *		  ----------------------------------------
 *		  Modification by Andy Tawse (andy.t@newmediacollective.com)
 *			getURL - when iterating through argArray to get variables to GET/POST, I've stopped it
 *						adding any functions that have been added to the array prototype
 *		  ----------------------------------------
 *
 *
 *        This class wraps the XMLHttpRequest object with a friendly API
 *        that makes complicated data requests trivial to impliment in
 *        your application.
 *
 *        USAGE:
 *            ----
 *            BASIC
 *            To instantiate the object, simply call it as a constructor:
 *
 *                var req = new DataRequestor();
 *
 *            Once you have the object instantiated, your usage will depend
 *            on your needs.  
 *
 *			  RETURNING TEXT
 *            If you want to grab data, and shove it wholesale into an element 
 *            on the page (which I do 90% of the time), then tell the DataRequestor
 *            object where to stick the info by passing setObjToReplace an
 *            element ID or object reference, and call getURL to complete the
 *            process:
 *
 *                req.setObjToReplace('objID');
 *                req.getURL(url);
 *
 *
 *            RETURNING A DOM OBJECT
 *            By default, the contents of the requested file will be passed in as
 *            plaintext, which can be simpler to work with than a real DOM object.
 *            If you'd like a DOM object to work with, then call getURL with
 *            _RETURN_AS_DOM as the second argument:
 *
 *                req.getURL(url, _RETURN_AS_DOM);
 *
 *            To avoid irritating problems, make sure you're sending a Content-type header
 *            of "text/xml" when you'd like your data processed as a DOM object.  IE gets
 *            confused otherwise.
 *
 *            RETURNING A JSON OBJECT
 *            If you've no idea what JSON is, visit http://www.json.org/
 *
 *            To get a JavaScript object back from DataRequestor, call getURL with
 *            with _RETURN_AS_JSON as the second parameter.
 *
 *                req.getURL(url, _RETURN_AS_JSON);
 *
 *            This, of course, assumes that you've generated a JSON string correctly
 *            at the URL you've requested.
 *            ----
 *            ARGUMENTS
 *
 *            To pass in GET or POST variables along with your request, use the
 *            addArg method:
 *
 *                req.addArg(argType, argName, argValue);
 *                e.g.
 *                req.addArg(_GET, "argument_number", "1");
 *
 *            addArg will automatically call escape() on the name and value to
 *            ensure they are URL escaped correctly.
 *            
 *            ARGUMENTS FROM A FORM
 *
 *            To pass in all the arguments from a form, use the `addArgsFromForm`
 *            method.  This will automatically call `addArg` on each of the form
 *            elements using the `method` attribute of the form to set the request 
 *            method for the arguments.  Each form element *must* have an ID for this
 *            method to function correctly.
 *
 *                req.addArgsFromForm(formID);
 *                e.g.
 *                req.addArgsFromForm("myFormName");
 *            ----
 *            EVENT HANDLERS
 *
 *                ON LOAD
 *
 *                To take action when the data loads successfully, set onload to a function that
 *                takes two arguments: data, and obj.  This will be called upon successful retrieval
 *                of the requested information, and will be passed the data retrieves and the object
 *                that will be replaced (or null if no replacement has been requested).
 *
 *                    req.onload = function (data, obj) {
 *                        alert("Callback handler called with the following data: \n" + data);
 *                    }
 *
 *                The first parameter (`data`) will be one of three things:
 *                    - text:  If getURL was called without a second argument, or _RETURN_AS_TEXT,
 *                      then `data` contains the raw text returned by the page that you loaded.
 *                    
 *                    - DOM object: If getURL was called with _RETURN_AS_DOM as the second argument, then
 *						`data` contains a DOM object, with blank whitespace nodes removed in order to 
 *                      provide a consistant experience between browsers that support the DOM standard
 *                      and IE.
 *
 *                    - JavaScript object: If getURL was called with _RETURN_AS_JSON as the second argument,
 *                      then `data` contains a JavaScript object generated from the JSON text that was returned
 *                      by the page you loaded.
 *
 *                ON REPLACE
 *                
 *                If you requested a replacement by setting an `objToReplace`, then this handler will
 *                be called directly after the replacement occurs, and will be passed the same variables
 *                as the `onload` method.
 *
 *                    req.onreplace = function (data, obj) {
 *                        alert("Callback handler called with the following data: \n" + data);
 *                    }
 *
 *                ERROR HANDLING
 *
 *                If the request fails, the XMLRequestor object defaults to simply throwing
 *                an error.  If that's not a great solution for you, then assign a function
 *                to onfail that accepts a single variable: the XMLHttpRequest status
 *                code.  Do with it what you will:
 *
 *                    req.onfail = function (status) {
 *                        alert("The handler died with a status of " + status);
 *                    }
 *
 *                PROGRESS
 *
 *                In Mozilla, it's possible to dynamically retrieve the amount of data that
 *                has been downloaded so far.  If you'd like to take an action on that data
 *                (e.g. set up some sort of progress bar) then set an onprogress handler that
 *                accepts two arguments, currentLength and totalLength.  Curiously enough,
 *                these arguments will be populated with the current amount of data that's been
 *                retrieved and the total size (or -1 if it can't be detected)
 *
 *                    req.onprogress = function (current, total) {
 *                        alert(current + " of " + total + " = " + ((total - current)/total) + "%");
 *                    }
 *
