#CRA-709 Bug in autocovariance estimation when all Vs logs are synthetic: fixed
Merge branch 'CRA-709' into CRA-505
CRA-723: Fixed bug where updated grids were not returned due to lacking reference, and wrong limit used in copy constructors for Simbox.

Merge pull request #139 from RagnarHauge/CRA-505

Cra 505 CRA-723: Initial fixes for running case 7 in multizone, still errors in output.
#CRA-709 Prior autocorrelation is computed as an average over all parameters in SeismicParametersHolder::InitializeCorrelations()
CRA-688, CRA-723: Added output_simbox to CommonData.
CRA-688, CRA-723: Updated the resampling algorithm in CravaResult. Changed so all resultsgrids are run through CombineResult, unless output_nz equals inversion_nz.

#CRA-709
CRA-645, CRA-652, CRA-688. CRA-723: Made fixes to resampling in CravaResult. Bug in analyzelog (vs_blocked). Removed ModelGeneral from graviystatic and dymanic.
CRA-619: Added SetupExtendedBackgroundSimbox based on two correlation direction.
CRA-723: Fixed a memory problem with resampling. Added blocked logs based on output simbox.
#CRA-717 Prior autocovariance is now linearly downscaled with vertical distance in seismicparametersholder.cpp instead of making a common autocorrelation function for the parameter covariance matrix
#CRA-716 Test case 5
