Local noise can not be used when wells are not given

Removed change from last commit
CRA-515
Make blocked logs to be used for estimation of rock physics variables.

Made class blockedlogsforrockphysics.h.

Made blockedLogs::findSizeAndBlockPointers() and blockedLogs::findBlockIJK() static such that they can be called from blockedlogsforrockphysics.cpp.

Include const std::vector<BlockedLogsForRockPhysics *> & blockedLogs in GenerateDistributionsRock(). The vector is over all facies. Need to include all facies as the rocks are built recursively.

Include rock name in each DistributionsRock... to find correct facies in the blocked logs.
CRA-515
Removed several class variables and made alpha_, beta_ and rho_ in blockedlogsforrockphysics.h std::vector<std::vector<float> > instead of std::vector<float *>.
CRA-515
Include blocked logs for the given facies into DistributionWithTrendStorage::GenerateDistributionWithTrend(). For solids, fluids and dry rocks, rock physics can not be estimated from wells; hence dummy variables are included.

Made BlockedLogs::blockContinuousLog(), blockDiscreteLog() and findMostProbable() static.
CRA-515

Include blocked_logs in all Trend...Storage::GenerateTrend().

First implementation of estimation of 1D trend.

Minor fixes

Make sure the same seed is used for all samples when (vp,vs,density) are sampled to make expectation and covariance for different trend values in DistributionsRock::SetupExpectationAndCovariances()
