- Removed Java-style iterators for Coordinates and PointCoordinates.
  std::vector has an expensive copy constructor and copy assignment.
  A pointer to std::vector is vulnerable to mysterious overwrites (e.g., deleting
  a returned value and reusing its memory).  Qt's 'foreach' should not be used for
  Coordinates and PointCoordinates.  It copies std::vector.
- QHULL_DECLARE_SEQUENTIAL_ITERATOR: allow temporary results
  The Jave-style iterator copies the container.  Same as Qt's Q_DECLARE_SEQUENTIAL_ITERATOR
- QhullHyperplaneIterator,QhullPointIterator,QhullPointsIterator: allow temporary results
  These Java-style iterators copy the container instead of pointing to the container
- QhullLinkedListIterator,QhullFacetListIterator,QhullVertexListIterator: allow temporary results
  These Java-style iterators copy the container instead of pointing to the container
- QhullSetIterator,QhullFacetSetIterator,QhullPointSetIterator,QhullVertexSetIterator: add documentation about temporary results
  These Java-style iterators have always copied the container
- QhullUser.h, user_eg3_r.cpp: Removed C++11 dependencies [S. Grein #66,#67]
  QhullUser.cpp: Use intptr_t to avoid C++11 dependencies  [S. Grein, Spacelm #68]
- QhullVertex.cpp: moved the copy constructor to the code file.  It was inline.

Testing and example programs
- user_eg3_r.cpp: Renamed 'inputSites' to 'voronoiRegions' in qvoronoi_o/qvoronoi_pfn [M. Konecny #72]
- user_eg3_r.cpp: Replaced C++11's range-based for loops with Qhull's Java-style iterators
- qh-code.html: Updated qhullcpp code example [M. Konecny #71]
- QhullFacet_test.cpp: fixed hyperplane epsilon test in t_getSet. The epsilon due to rotation is unknown.
- Qhull*List_test.cpp,Qhull*Set_test.cpp,QhullRidge_test,QhullVertex_test: test Qt's 'foreach' in t_foreach
- Qhull*List_test.cpp,Qhull*Set_test.cpp,QhullRidge_test,QhullVertex_test: test C++11 range for in t_foreach
- Qhull*List_test.cpp,Qhull*Set_test.cpp: test Java-style iterator in t_java_iterator
- Coordinates_test.cpp,PointCoordinates_test.cpp,QhullHyperplane_test.cpp,QhullPoint_test.cpp,QhullPoints_test.cpp,RboxPoints_test.cpp
  test C++11 range for, Qt's 'foreach', and Java-style iterators (if available)
