 * Summary: Cross-browser wrapper for DOMContentLoaded

 *
 * Full Description:
 * A page has loaded after all external resources like images have been loaded.
 * Should all scripts wait for that? a better bevaviour is to wait for the dom content being ready.
 *
 * This script has workarounds for all the big browsers meaning the major versions of firefox, internet explorer, opera, safari and chrome.
 * You can use it without risk, since the normal "onload" behavior is the fallback solution.
 *
 * Most of the source is lended from jquery
