// Virtual Pagination Script- By Dynamic Drive, available at: http://www.dynamicdrive.com
// Last 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).
