GeographicLib 1.42 (released 2015-04-28)

Changes between 1.42 (released 2015-04-28) and 1.41 versions:

• DMS::Decode allows a single addition or subtraction operation, e.g.,
  70W+0:0:15. This affects the GeoCoords class and the utilities
  (which use the DMS class for reading coordinates).

• Add Math::norm, Math::AngRound, Math::tand, Math::atan2d,
  Math::eatanhe, Math::taupf, Math::tauf, Math::fma and remove
  duplicated (but private) functionality from other classes.

• On non-Windows systems, the cmake config-style find_package files
  are now installed under ${CMAKE_INSTALL_PREFIX}/lib${LIB_SUFFIX}
  instead of ${CMAKE_INSTALL_PREFIX}/share, because the files are
  architecture-specific. This change will let 32-bit and 64-bit
  versions coexist on the same machine (in lib and lib64). You should
  remove the versions in the old "share" location.

• MATLAB changes:

  • provide native MATLAB implementations for compiled interface
    functions;
  • the compiled MATLAB interface is now deprecated and so the
    MATLAB_COMPILER option in the cmake build has been removed;
  • reorganize directories, so that
    o matlab/geographiclib contains the native matlab code;
    o matlab/geographiclib-legacy contains wrapper functions to mimic
    the previous compiled functionality;
  • the installed MATLAB code mirrors this layout, but the parent
    installation directory on non-Windows systems is
    ${CMAKE_INSTALL_PREFIX}/share (instead of
    ${CMAKE_INSTALL_PREFIX}/libexec), because the files are now
    architecture independent;
  • matlab/geographiclib is now packaged and distributed as MATLAB
    File Exchange package 50605 (this supersedes three earlier MATLAB
    packages);
  • point fix for geodarea.m to correct bug in area of polygons which
    encircle a pole multiple times (released as version 1.41.1 of
    MATLAB File Exchange package 39108, 2014-04-22).

• artifactId for Java package changed from GeographicLib to
  GeographicLib-Java and the package is now depolyed to Maven Central
  (thanks to Chris Bennight for help on this).

• Fix autoconf mismatch of version numbers (which were inconsistent in
  versions 1.40 and 1.41).

• Mark the computation of the gradient of the geoid height in the
  Geoid class and the GeoidEval utility
  as deprecated.

• Work around the boost-quadmath bug with setprecision(0).

• Deprecate use of Visual Studio 2005 "-vc8" project files in the
  windows directory.
