Message:

Pair correlation analysis added.

• new file analysis_correlation.cpp with the following functions: PairCorrelation(), CorrelationToPoint(), CorrelationToSurface(), GetBin(), OutputCorrelation(), and templates GetMinMax(), BinData()
• three new unit tests: AnalysisCorrelationToPointUnitTest AnalysisCorrelationToSurfaceUnitTest AnalysisPairCorrelationUnitTest (each in own file)
• new function DistanceToTrianglePlane() in tesselationhelpers.cpp
• new function Vector::DistanceToPlane() calculates distance to a plane

Unit tests are working fine.
