- Updating Noble 1962 model:
* Exposing the membrane potential to the top-level model;
* adding SED-ML for the paced and pacemaker variants of the model.
Using OpenCOR Snapshot release 2021-09-14.

dojo.provide("dojox.io.windowName");
// Implements the window.name transport
dojox.io.windowName = {
send: function(/*String*/ method, /*dojo.__IoArgs*/ args){
// summary:
// Provides secure cross-domain request capability.
// Sends a request using an iframe (POST or GET) and reads the response through the
// frame's window.name.
//
// method:
// The method to use to send the request, GET or POST
//
// args:
// See dojo.xhr
//
// args.authElement: DOMNode?
// By providing an authElement, this indicates that windowName should use the
// authorized window.name protocol, relying on
// the loaded XD resource to return to the provided return URL on completion
// of authorization/authentication. The provided authElement will be used to place
// the iframe in, so the user can interact with the server resource for authentication
// and/or authorization to access the resource.
//
// args.onAuthLoad: Function?
// When using authorized access to resources, this function will be called when the
// authorization page has been loaded. (When authorization is actually completed,
// the deferred callback function is called with the result). The primary use for this
// is to make the authElement visible to the user once the resource has loaded
// (this can be preferable to showing the iframe while the resource is loading
// since it may not require authorization, it may simply return the resource).
//
// description:
// In order to provide a windowname transport accessible resources/web services, a server
// should check for the presence of a parameter window.name=true and if a request includes
// such a parameter, it should respond to the request with an HTML
// document that sets it's window.name to the string that is to be
// delivered to the client. For example, if a client makes a window.name request like:
// | http://othersite.com/greeting?windowname=true
// And server wants to respond to the client with "Hello", it should return an html page:
// | <html><script type="text/javascript">
// | window.name="Hello";
// | </script></html>
// One can provide XML or JSON data by simply quoting the data as a string, and parsing the data
// on the client.
// If you use the authorization window.name protocol, the requester should include an
// authElement element in the args, and a request will be created like:
// | http://othersite.com/greeting?windowname=auth
// And the server can respond like this:
// | <html><script type="text/javascript">
// | var loc = window.name;
// | authorizationButton.onclick = function(){
// | window.name="Hello";
// | location = loc;
// | };
// | </script></html>
