Message:

Huge refactoring of Tesselation routines, but not finished yet.

• new file tesselation.cpp with all of classes tesselation, Boundary..Set and CandidatesForTesselationOB
• new file tesselationhelper.cpp with all auxiliary functions.
• boundary.cpp just contains super functions, combininb molecule and Tesselation pointers
• new pointer molecule::TesselStruct
• PointMap, LineMap, TriangleMap DistanceMap have been moved from molecules.hpp to tesselation.hpp
• new abstract class PointCloud and TesselPoint
• atom inherits TesselPoint
• molecule inherits PointCloud (i.e. a set of TesselPoints) and implements all virtual functions for the chained list
• TriangleFilesWritten is thrown out, intermediate steps are written in find_nonconvex_border and not in find_next_triangle()
• LinkedCell class uses TesselPoint as its nodes, i.e. as long as any class inherits TesselPoint, it may make use of LinkedCell as well and a PointCloud is used to initialize
• class atom and bond definitions have been moved to own header files

NOTE: This is not bugfree yet. Tesselation of heptan produces way too many triangles, but runs without faults or leaks.

• molecuilder/src/molecules.cpp (modified) (2 diffs)
