  // Here is a typical code call to retrieve a value within a querystring like: ?name=SOMENAME&email=SOMEEMAILADDRESS
  // The JS code to retrieve the *name* value and assign it to a variable named TheQueryStringValueFor_name would be:
  // TheQueryStringValueFor_name = returnMatchingQueryStringValueForSpecificQueryVariableName("name");
  //
  // This code ONLY works ONLINE.
