SGP AF Logviewer v1.2 Release

I want to highlight the ability to read and analyse many logfiles, by showing the result of a bunch of log files (22 files !) provided by @bvalente . These include a total of 410 AF runs!, spanning more than 1 month. The resulting position vs temperature analysis is quite amazing, with a very accurate fit of the linear slope that is used for temperature compensation in SGP.
