Fixes for concave hull creation

• fixed BoundaryLineSet::CheckConvexityCriterion(), we now compare the two heights of the triangles, not the NormalVector which was nonsense
• new functions BoundaryLineSet::GetOtherEndpoint(), BoundaryTriangleSet::GetThirdEndpoint()
• Tesselation::InsertStraddlingPoints() receives LinkedCell pointer and uses FindClosestTrianglesToPoint(), and some verbosity added
• generally replaced [aA]tom by [pPoint]
• Tesselation::CorrectConcaveBaselines() (almost) corrected
• IsInnerPoint is overloaded function which calls FindClosestTriangleToPoint() to decide
• getAngle() receives references instead of copies with exception of OrthogonalVector which is made orthonormal to reference - center (is a FIX)
