Geocaching True Totals - v1.0 2005-10-20
(c) 2005, Prime Suspect Software

Greasemonkey user script: see http://greasemonkey.mozdev.org

Function:
 Copies 'Show All Logs' link above the logs. When all logs are 
 displayed, a breakdown of totals by log type is shown
 above the logs.
 
Usage:
 When link to show all logs is clicked, after loading, the page 
 will be repositioned to the start of the logs. 'Show All Logs' 
 link will be replaced by the type totals. If there are 5 or fewer 
 logs for a cache, the totals by type will automatically be show.
