Replace Delaunay_triangulation_off_io.h and Delaunay_triangulation_off_rw.cpp with

        Points_off_io.h and CGAL_points_off_reader.cpp
Adapt UT and examples for this
Adapt Alpha complex for it
Alpha complex is now inserting points in a faster way (after a spatial_sort).
Remove Alpha complex construction from a pointer on Delaunay triangulation (no more needed).
Adapt documentation to all these modifications
Forbid copy/move constructor/assignment operator on Alpha complex
