//   and note any changes in the Additional Notes section, get
//   the most up-to-date/pure version at walzguitar.com
// - this widget provides a simple API to use this widget, the widget
//    will insert style and form tags for a multi site search box
//
// SIMPLE USE------------------------------------------------------------------
//  - copy the 3 lines below and paste where you want the widget to 
// appear, then remove the comment, //, marks
//<script type="text/javascript">
//WG_ss.writeHTML( );
//</script>
//
// ADVANCED USE----------------------------------------------------------------
// - WG_ss is the default variable reference for the widget object 
// - available function list
//    1 WG_ss.setStyleOverride(boolean)  pass true or false, true will 
//       override the automatic style so you set your own styling, ids 
//       below:
//         - wgform = form, wgq = input for query, wgsel = select control
//         - wgb = input button
//    2 WG_ss.setWidth([0-9][0-9]*)  pass a number, the default is 150px, 
//       this number passed defines the pixel width, this doesn't work in 
//       Chrome
//    3 WG_ss.getRawHTML()  gets the raw, unstyled HTML for the widget
//    4 WG_ss.writeHTML()  uses the document.write function to write the 
//       widget HTML to the document
//    5 WG_ss.setElementHTML(id)  uses the innerHTML property of the element 
//       to set the HTML, use after the element has loaded
//
// ADDITIONAL NOTES------------------------------------------------------------
// - 2009/06/11 Did a long needed fix that affected the Fretplay search.  
//              Added a global replacement of spaces to + symbols in search 
//              queries. Fixed some comment typos and added sites and function.
//
