RandomLib 1.6 (released 2012-09-13)

This is a maintenance release. Changes

• Documentation changes:
  • remove html documentation from distribution and use web links if
    doxygen is not available;
  • use doxygen tags to document exceptions;
  • use Greek letters where appropriate (requires doxygen 1.8.1.2 or
    later);
  • use MathJax to display equations.
• Support building with cygwin and mingw32-g++ on Windows (via
  cmake).
• Releases via git now use the "release" branch of the main
  randomlib repository (instead of a separate randomlib-release
  repository).
