//
// Remarks:
// This code has been adapted from nl.sitestat.com and www.nedstat.com, 
// in order to allow it being executed unobtrusively.
// It is added to the LecJS javascript object defined elsewhere.
//
// Usage:
// Add a script element to the page in which this script should run.
// Add it after the script element that loads the LecJS object.
// This is unobtrusive javascript, meaning Smartsite's header deference won't work.
