* @param {Object} [headers] HTTP headers to send with the request.
* @returns {Promise.<String>} a promise that will resolve to the requested data when loaded.

* @example
* // load text from a URL, setting a custom header
* Cesium.loadText('http://someUrl.com/someJson.txt', {
* 'X-Custom-Header' : 'some value'
* }).then(function(text) {
* // Do something with the text
