// -------------------------------------------------------------------
// Virtual Pagination Script- By Dynamic Drive, available at: http://www.dynamicdrive.com
// Updated: Nov 21st, 2008 to v2.0
// ** Adds ability to define multiple pagination DIVs (the secondary DIVs mirror primary DIV's contents)
// ** Last viewed page persistence, so last viewed page can be remembered/ recalled within browser session.
// ** Improvements to instance.navigate() to select a page using an arbitrary link or inside another script.
// ** Ability to select a page using a URL parameter (ie: target.htm?virtualpiececlass=index).

// Updated: Oct 19th, 2009 to v2.1
// ** New wraparound:true/false option added, which when false disables moving back/forth beyond first and last content, respectively
//

// Main Virtual Paginate Object function.
