Move class objects after fields in .h files
Added more changes.txt
Changed version to 2009.0.1

Breaking change
  Renamed qhulllib to libqhull to match libqhull.a
  Keep rboxlib as is.  librbox does not scan and rbox is not a lib

it always includes userprintf and usermem.c

Something is wrong since qhull-qt tries to load a dll

Also ConvexHull is a submodule when it shouldn't appear at all.  This causes
problems with switching between branches.

Qhull and rbox build correctly under mingw with gcc 4.4.0.  Please
send email to bradb@shore.net if Qhull builds correctly with Linux
gcc 4.4.0 -O2.   With gcc 4.2 and 4.3 qset.c segfaulted due to an
optimization error.

      [April 2008] of http://www.qhull.org/news/#bugs

user_eg3 is a demonstration of using Qhull C++ interface.

Qhulltest contains some failing testcases due to changes made for user_eg3.
Will be fixed soon.

qhull-qt reports an error because the link does not skip userprintf.c
in libqhull.a.  Also the dependencies between qhull-qt and libqhull.a
are handled incorrectly.

Includes QTest files for each class and user-eg3.c for demonstrating the interface.
See src/Changes.txt for change notes and to do.

See WARN64 for 64-bit problems

New Features:
 - Add Maple output ('FM') for 2-d and 3-d convex hulls [T. Abraham]

Breaking Code Changes:
 - Annotate C code with 'const'.  An ANSI compatible compiler is required.

Bug Fixes and Code Changes:
 - Fixed qh_findbest() for upperdelaunay facets w/o better, lower neighbors
     For library users and some qhull users [A. Cutti, E. Milloti, K. Sun]
 - Preserved qhmem.ferr in qh_memfreeshort() for library users
 - Removed 'static' from qh_compare... for io.h and merge.h [V. Brumberg]
 - Split out qh_initqhull_start2() to avoid allocating qh_qh
 - Split out qh_freeqhull2() to avoid freeing qh_qh
 - Split out qh_produce_output2() and qh_prepare_output()
 - qh_initstatistics() frees a previously existing qh_qhstat
 - qh_initqhull_start2() checks that qh_initstatistics() called first

Documentation:
 - Add warning to findDelaunay() and qh_in.htm about tricoplanar facets
 - Noted Edelsbrunner's Geometry & Topology for Mesh Generation [qh-impre.htm]
 - Noted Gartner's Miniball algorithm [qh_impre.htm]
 - Noted Veron and Leon's shape preserving simplification [qh_impre.htm]

qhull 2003.1  2003/12/19

Bug Fixes:
 - Reversed coordinate order for qh.ATinfinity in qh_projectinput [V. Brumberg]
   This effects:
     Qhull library 'd' or 'v' users with 'Qz' and unequal coordinate ranges.
     qdelaunay/qvoronoi users with 'Qbk:0Bk:0', 'Qz', and unequal coordinate ranges

Changes to code:
 - Replaced qh_VERSION with qh_version in global.c [B. Pearlmutter]
    The previous techniques were either clumsy or caused compiler errors
 - Removed unused variables from qh_findbest and qh_findbestnew [B. Pearlmutter]
 - Note that qh.TESTpoints was added in 2002.1 for tsearch implementation

Changes to distribution:
 - Added Unix distribution including Debian files [R. Laboissiere]
    The previous Unix distribution is now the source distribution
 - Added rpm distribution [L. Mazet]
 - Investigated generation of Win32 dll.  Need to define a C++ interface.

Changes to documentation:
 - Moved Qhull to www.qhull.org (geom.umn.edu is not available)
 - The Geometry Center is archived at http://www.geom.uiuc.edu
 - Reviewed introduction to each program
    Triangulated output ('Qt') is more accurate than joggled input ('QJ')
    qdelaunay is 'qhull d Qbb' [C. Ulbrich]
    qvoronoi is 'qhull v Qbb'
    Added example of non-simplicial intersection to halfspace intersections
 - Added warning about using the Qhull library.
 - Added qhull timings to When to use Qhull [C. Ulbrich]
 - Reorganized the home page index and the manual index
 - Moved qh-home.htm to index.htm

Changes to examples
 - Fixed options for eg/eg.t23.voronoi.imprecise [B. Pearlmutter]

Changes to distribution:
 - Set up savannah.nongnu.org/projects/qhull/ [R. Laboissiere]
 - Set up www.thesa.com as a backup
 - Added qh-get.htm, a local copy of the download page
 - Added Visual C++ interface to Qhull, qhull_interface.cpp [K. Erleben]
 - Use HTTP instead of FTP for downloading Qhull
 - Renamed qhull-1.0.sit.hqx

Bug fixes:
 - Fixed sign of coefficients for cdd halfspaces ('FD','Fd')  [T. Abraham]

Changes to code:
 - Replace qh_version with qh_VERSION in qhulllib.h.
   Allows shared libraries and single point of definition
 - Added qh.TESTpoints for future implementation of tsearch

Changes to build
 - Makefile.txt works under cygwin
 - Added Make-config.sh to create a Debian build [R. Laboissiere]
 - Added .exe to Makefile.txt#clean.
 - In README, use -fno-strict-aliasing with gcc-2.95.1 [Karas, Krishnaswami]
 - Fixed chmod in Makefile.txt [B. Karas]
