/**
 * Loop Pagination - A WordPress script for creating paginated links on archive-type pages.
 *
 * The Loop Pagination script was designed to give theme authors a quick way to paginate archive-type 
 * (archive, search, and blog) pages without having to worry about which of the many plugins a user might 
 * possibly be using.  Instead, they can simply build pagination right into their themes.
