…vertex info Expose Triangulation_vertex_base_with_info_3 and Delaunay_triangulation_cell_base_3 via a new Delaunay_triangulation_3_with_info binding. Fixes CGAL#288
…vertex info Expose Delaunay_triangulation_3_with_info to allow users to attach custom double data to triangulation vertices from Python. Add new typedefs in typedefs.h and declare the new class in CGAL_Triangulation_3.i outside the USER_PACKAGE ifdef block. Add Python example and test. Fixes CGAL#288

Description:
Fixes #288
Problem
Users cannot attach custom data (e.g. float/double values) to
triangulation vertices from Python because these classes were
missing from the SWIG interface:
Solution
typedefs.hfor a newCGAL_DT3_with_infotype usingdoubleas vertex infoDelaunay_triangulation_3_with_infoclass inCGAL_Triangulation_3.ioutside the USER_PACKAGE ifdef blocktest_triangulation_3_with_info.pywith a working test (6 vertices inserted and verified)
Testing
Tested locally — build succeeds and test passes:
Number of vertices: 6
Test passed!
