Added new functions to datacage templating language. * get minimum of location/distance: dc:fromValue($ld_mode, $ld_locations, $ld_from) - returns -Double.MAX_VALUE if no min exists. * get maximum of location/distance: dc:toValue($ld_mode, $ld_locations, $ld_to) - returns Double.MAX_VALUE if no max exists.
