Lots of work to clean up and make it actually do rough calibration.

Switch to hard-coded fields on log entries.  It makes query composition way easier to read.  Renamed all of the controls.. but that's just me being pedantic.  Clean up incoming headers to match better with our defined maps.  Added in a first pass at closed loop calibration - for every long line we have that is presumed to be in closed loop, we find the closest calibration point for the given MAF voltage, and for each calibration point where we have an LTFT value, or multiple LTFT values, we average them before applying the adjustment.
