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-506 Fixed warning messages in test suite related to the xml file
CRA-529 Fixed undefsum problem (hopefully)
CRA-515

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

First implementation of estimation of 1D trend.
