/**
* Shows the jumper. This jumper works for pages that process a get request. The page must put the all results in
* the node with id "{$id_base}_results". The jumper is placed in the node with id "{$id_base}_pager_display". It
* is expected that the node with id "{$id_base}_pager_display" is a sub-node of the node with id "{$id_base}_results".
* Note: there will be several nodes created with id's of the form "{$id_base}_pager_$something" so with the exception
* of $something='display' you should not use id's of this form.
*
* This fuzzy method can be called either from an I2CE_Page or an I2CE_Template.
*
* @param string $id_base the base id that should be used in identifying the node to update (e.g. 'report')
* @param array $jumps array of int, the pages we want in the jumper. Does not inclu
* @param int $page the current page number
* @param int $total_pages the total numnber pf pages
* @param string $pageURL the url of the page we will make the request from
* @param associatibe array $query_fields keys are the query variables needed for the get request. values are the _unencoded_ values that
* the variable should have.
* @param string $pageVaraiable the get variable to store the requested page number in. Defaults to 'page'
