* Rename from DiffCurve to CalculatedCurve and add operators selection
* Add option to select depth source for resampling in CalculatedCurve
- Select source for depth values for resampling
- Depths from first curve, second curve or union of these
- Added unit tests for function creating union depth values and calculate value with selected operator.
* Guard divide by zero
* Adjust algorithm for union of depths
- Prevent duplicated depth values (no need for enter/exist of k-layer when resampling)
- Add threshold for depth distance
- Update unit tests
* RFT curves: Disable auto color by default
* RFT curves: Fix wiggling legend caused by too many plot updates
* RFT Curves: Search multiple layers for CONFAC data
* Move plot orientation to Depth Axis, Advanced group
- add CONGRAT
- add pressure track
- add CONFAC
- fix some plot layout issues
- Fix bug for first segment MD location
- Add default scale factor 1e-3 for gas curves
- Avoid inf values in some curves, seen in PRESSURE and CONFAC
- Use assignment in statements instead of std::get
* Add topology curves and default plot
* Improve visual appearance
* Update sub module opm-common
* Add support for INCLUDE keyword to allow parsing of include files recursively
* Search for *.DATA with fallback to *.SCH to automatically import WESEGLINK data
* Find annulus branch based on MD diff on segment start
* Stop growing device branch if segment starts at a lower MD than previous
* Add create plot with RFT curve
* Add RFT segment plot with curve
* Create tracks for all three branch types
* Make sure the zero is displayed when adjusted minimum is changing sign
