Message:

Multi-Candidate-Add included and incorporated class Info into boundary.cpp, tesselation.cpp and tesselationhelpers.cpp

• class Info incorporation:
  • (almost) all functions of boundary.cpp, tesselation.cpp and tesselationhelpers.cpp now begins with class Info FunctionName(func);

• Multi-Candidate-Add:
  • CandidateForTesselation now contains a pointlist instead of a single point
  • Tesselation::AddCandidateTriangle() adds an polygon (for multiple candidates) instead of a single triangle.
  • HasOtherBaselineBetterCandidate() was commented out (it is to be checked whether we really need this)
  • Tesselation::FindNextSuitableTriangle() is reduced to pre-calculation of centers and calling Tesselation::FindThirdPointForTesselation()
  • Tesselation::FindThirdPointForTesselation() now fills the CandidateForTesselation::pointlist
  • Tesselation::FindStartingTriangle() now creates a CandidateForTesselation inside the NDIM-loop and Tesselation::FindThirdPointForTesselation() fills it.
