//  ShowLatest simply shows the latest readings,

//   It is an exact replica of mobile.php with different formatting

//  Optional parameter sensor: name of requested sensor
//    If such a sensor exists, then just the latest temperature is displayed, eg: 
//          showlatest.php?sensor=Aquarium

//  Example NAGIOS command definition:
//    define command {
//      command_name    check_dtgraph_alarms
//      command_line    curl -s http://$HOSTADDRESS$/dtgraph/showlatest.php 2>/dev/null | grep ALARM && exit 2
