/**
 * The built-in pagination functions provide either two buttons (forward / back)
 * or lots of buttons (forward, back, first, last and individual pages). This
 * plug-in meets the two in the middle providing navigation controls for
 * forward, back, first and last.
 *
 * DataTables has this ability built in using the `dt-string full` option of
 * the `dt-init pagingType` initialisation option. As such, this plug-in is
 * marked as deprecated.
