--!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
--!!!! create special function with switch ON to run the script 'logchx' !!!!
--!!!! this function MUST come before any channeloverride function       !!!!
--!!!! any channeloverridefunction MUST be triggered by a LOGICAL switch !!!!
--!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
--
--detect sensors.
--after detection, delete current logfile
--this to allow the new columns to be created correctly in the new logfile.

--Logs will contain ppm value
--PPMCENTER WILL BE INCLUDED 


--!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
--improved help and gVar support available
--typos fixed
--V1.4 NO CURVES SUPPORTED
--!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
--include ChannelOverRide detection
--V1.5 NO CURVES SUPPORTED
--!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

--!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
--!!!! LUA doesn't allow to get the channelOverRide function number    !!!!!!
--!!!! add in the BUGSOLVE list all SFlines with the ChannelOverRide # !!!!!!
--!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
--include ChannelOverRide detection BUGSOLVE workaround
--V1.6 NO CURVES SUPPORTED
