[Therion] Compile error do to "calibrate" command

[Torsten Schnitter]

Quantity List doesn't contain fromdepth or todepth. But only depth.

Btw with "calibrate depth 0 -1" there is no error while compiling.

Survex follows the convention used with scientific instruments - the ZeroError is what the instrument reads when measuring a reading which should be zero. So for example, if your tape measure has the end missing, and you are using the 30cm mark to take all measurements from, then a zero distance would be measured as 30cm and you would correct this with:

Since Survex 1.2.22, it’s recommended to instead use the new *declination command instead - see the documentation of that command for more details.
