// ---------------------------------------------------------------------------------------------------------------------
// PromiseProxy - A proxy object that wraps a promise, and exposes `pending`, `result` and `error` properties. This is
// most useful when setting results of promises on the scope directly, so you can work with them in your templates.
//
// @module promise-proxy.js
// ---------------------------------------------------------------------------------------------------------------------

function PromiseProxyFactory(promise)
{
    var proxy = {
        pending: true,
        promise: promise
    };

    promise.then(
        function(result)
        {
            proxy.result = result;
        },
        function(error)
        {
           proxy.error = error;
        });

    return proxy;
