- Adds 'std=c++11' compiler flags - Replaces boost::type_traits with std::type_traits - Replaces boost::shared_ptr with std::shared_ptr - Replaces std::auto_ptr with std::unique_ptr - Replaces raw pointers with std::unique_ptr in ptr_vector, ptr_stack, and SettingChanges - Replaces boost::noncopyable with deleted copy and assignment operators - Replaces boost::next with std::next - Replaces boost::enable_if with std::enable_if - Replaces boost::is_convertible with std::is_convertible - Replaces ptrdiff_t with std::ptrdiff_t - Replaces boost::iterator_facade and boost::iterator_adaptor with std::iterator, borrowing the 'proxy reference' technique from boost - Removes Boost dependency from CMakeLists - Formats changed files using clang-format
