documentation, some renames (..Triangle.. -> ..Tesselation..) and a bunch of new functions needed for ConvexizeNonconvexEnvelope()

• all of function documentation in place
• AddTriangle...() is now called AddTesselation...() which makes more sense, as they mainly add points, lines and triangles to the global tesselation lists
• New functions RemoveTesselation...() that erase points, lines and triangles and are counterparts to the AddTesselation...() functions (Note: They mostly do what the destructors did, only they erase also from global lists by not calling delete for subelements, but RemoveTesselation...() which does the job)
• ~BoundaryLineSet() checks whether both endpoints are still present, is more robust, as they may be missing from RemoveTesselation...()
• ~BoundaryTriangleSet() checks earlier whether lines are still present, same argument
• AddPoint() is now called AddBoundaryPoint(), works on *BPS array, AddTesselation...() work on *TPS array -> cleaner separation
• new function Tesselation::IsConvexRectangle() checks whether the rectangle made out of the four points of the two triangles with the same baseline in between, is convex or concave. this is needed for ConvexizeNonconvexEnvelope()
• Tesselation::CorrectConcaveBaselines() renamed to Tesselation::PickFarthestofTwoBaselines, which uses GetClosestPointBetweenLine() to check whether one baseline is above the other with respect to the BaseLineNormal vector and always modies the tesselation so that the higher one is used.
• new function GetClosestPointBetweenLine() which calculates the closest point on a line with respect to another line.
• new function Tesselation::FlipBaseline() does most of what CorrectConcaveBaseLine() did before only without the Convexity check (is done in boundary.cpp:Convexize...())
• Tesselation::GetCircleOfConnectedPoints() renamed to Tesselation::getNeighboursonCircleofConnectedPoints() and new function Tesselation::GetCircleOfConnectedPoints() which really returns just the circle of points, the renamed function works on the result of the new one.
• new function Tesselation::RemovePointFromTesselatedSurface() which just removes the point, re-creating its triangles with the remainder of the points to keep the surface closed.
