CRA-679: Started making multintervalgrid a general class. Added a copy constructor.
CRA-505: Merge with enesvold (#96).
CRA-561, CRA-568, CRA-679: Made MuliIntervalGrid a class for only interval-information. Moved parameters (background, priorfacies, trendcubes) to CommonData.
CRA-505: Removed getTimeNz from modelSettings, only use getTimeNzIntervals.
CRA-505: Removed include background.h.
CRA-505: Fixed a bug with ReadVolumeFromFile.
CRA-679: Adjusted SetupBackground and SetupPriorFacies to new MultiIntervalGrid.
CRA-553, CRA-679: Background grid was allocated twice. Removed functions in multiintervalgrid.

CRA-505: Merge with RHauge (97).
CRA-505: Merge with enesvold (98).
CRA-505: removed some include files.
CRA-505: removed some include files.
CRA-681: Combined the two variables (single or multi interval) for prior facies from file in ModelSettings. Checks are made against all intervals.
CRA-505: Only print out interval name if multiple intervals in MultiIntervalGrid.

CRA-680: Changed blocked logs in SetupPriorFaciesProb to logs blocked to interval simbox.
CRA-546: Added copy of waveletscale when wavelet_pre_resampled is copied.
CRA-505: Removed old functions from model-files that was no longer in use and was already commented out.
CRA-683: Fixed the problem with dz not set, and at the same time removed bug where ModelAVODynamic crashed when wavelet was from file.

Note that this does not solve the problem in CRA-683, as there still is a scaling issue between wells and seismic data. (Location of seismic data is given in km, wells in m)
