AUTO INDOOR MODE
AUTO INDOOR mode allows auto filling of measurement points when the GPS fix is not available like in tunnels or on places with bad GPS reception.

AUTO INDOOR mode works only when the log is active.
If INDOOR mode is selected AUTO INDOOR mode is not activated.

How to use it:
1. Enable AUTO INDOOR mode in Settings.
2. Choose threshold for GPS validity
3. Start log.
4. When you enter the tunnel and lose GPS fix the GPS writing on upper right corner of MAP tab will color in blue which means that AUTO INDOOR mode is active and measurements are collected.

5. When you go out of the tunnel and GPS fix is valid the values for GPS accuracy and time are colored in green, the exiting point is auto set and the missing measurements between entering and exiting point are shown on the map and filled in the log.

Loading Floorplans
Load floorplan from image files located in \floorplan folder. Index file index.txt describing edge locations also should be present in the folder

How to load floorplans:
1. In folder G_NetWiFi_Pro_Logs/floorplan put the floorplan images and create text index file (index.txt) with rows for each image and following content (tab delimited)
