If the soundsource does not have applied values, the measured soundspeed will be used in the TOA edit window.

Bugfix, the reload functions now restore either float or soundsources applied values after reloading.

The soundsource combinations table now has a "use" boolean for enabling/disabling the combination during tracking.

Added a new column to the tracking parameter panel ReferencePositionEnd. Adjusted the tracking algorithms accordingly.

Added first version of the new backward tracking method. It is now possible to use interpolation methods as well.

Bugfix, Plotting the soundsource line segments used a wrong algorithm to estimate the already processed combinations.

The soundsource combination panel now shows the segment color as background if the "Update track parameter" is enabled in trajectory output.

The offsets get recalculated.

Integrated the empiric_offset and empiric_drift parameter of the float, Changed copy offsets layout.
