Summary of Changes

Instead of changing the API of TDS, Triangulation, and everything using it, this PR takes another approach:
We store indices in the data structures instead of handles, and generate the handles on the fly, which hold a pointer to the TDS and an index.

We also split Triangulation_data_structure_3 in two: A base class which knows about storage and index/vs pointer and provides an API with handles. And a derived class that uses this API with handles, which works for both base classes as in the derived class we do not use pointers or indices directly.

We checked that the Triangulation with indexed storage can be used in Alpha Wrapping without as only change of code the typedef of the TDS.

Todo

See tracking issue #8969.
