/*
 * a backwards compatable implementation of postMessage
 * by Josh Fraser (joshfraser.com)
 * released under the Apache 2.0 license.
 *
 * this code was adapted from Ben Alman's jQuery postMessage code found at:
 * http://benalman.com/projects/jquery-postmessage-plugin/
 *
 * other inspiration was taken from Luke Shepard's code for Facebook Connect:
 * http://github.com/facebook/connect-js/blob/master/src/core/xd.js
 *
 * the goal of this project was to make a backwards compatable version of postMessage
 * without having any dependency on jQuery or the FB Connect libraries
 *
 * my goal was to keep this as terse as possible since my own purpose was to use this
 * as part of a distributed widget where filesize could be sensative.
