Message:

Fix attempts of the Tesselation.

One problem still remains:

• degenerated triangles are created more than two times.

The following has been changed:

• BondGraph::~BondGraph() - docu changes
• FindNonConvexBorder() - added CheckListOfBaseLines() and StoreTrianglesInFile() before CorrectDegeneratePolygons() (allows checking of closed tesselation even when correction fails)
• boundary.hpp: SingleStepWidth set to 10
• Tesselation::AddTesselationLine() - FindLine set before if and hence we may use it twice and find() only once
• Tesselation::FindStartingTriangle() - renaming of variables such that they are equal to FindNextSuitableTriangle()
• Tesselation::FindNextSuitableTriangle() - using SphereCenter (is the result of GetCenterofCircumcenter())
• Tesselation::FindThirdPointForTesselation() - some rewrites to make the code clearer
• CandidateForTesselation::IsDegenerated - designates candidate TesselPoint of a degenerated triangle
• BoundaryTriangleSet::SphereCenter - contains the SphereCenter created during Tesselation of the triangle
• FIX: Tesselation::CorrectAllDegeneratedPolygons() - only adds triangles to candidate list that are _not_ simply degenerated (this prevents two(four) singly degenerated but separate triangles to be put into the same polygon, resulting in an uneven number of triangles).
• new function Vector::IsEqualTo() - checks whether vector is equal to another (within MYEPSILON bounds)
