/**
* 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.
