// jquery extension to easily get request parameter name value pairs w/out hassle of parsing.  http://jquery-howto.blogspot.com/2009/09/get-url-parameters-values-with-jquery.html
// usage:
//   Get object of URL parameters would be this (without comments of course):
//   var allVars = $.getUrlVars();
//   Getting URL var by its name - the name of the parameter
//   var byName = $.getUrlVar('name');
//  example: if url was this: http://us.ishares.com/misc/faq.htm?id=q1&name=john
//           var allVars = $.getUrlVars() would return {"id"  : "q1", "name" : "john" }
//           var byName = $.getUrlVars('name') would return {"john" }
