+       DocumentReady Plug-in
+       
+       This plugin loads SWFUpload as soon as the document is ready.  You should not load SWFUpload inside window.onload using this plugin.
+       You can also chain other functions by calling SWFUpload.DocumentReady(your function).
+       
+       Warning: Embedded Ads or other scripts that overwrite window.onload or use their own document ready functions may interfer with this plugin.  You
+               should not set window.onload when using this plugin.
+       
+       Usage Example:
+       
+       var swfu = new SWFUpload(your settings object);
+       SWFUpload.DocumentReady(function () { alert('Document Ready!'; });
+
