* now building in c++14 mode (requiring clang 3.4)
 * replaced all functor uses with std::function/bind uses
 * replaced a few "type*" vars with "vector<type>", so a manual "delete []" call isn't necessary any more
 * removed unused normal_list from a2estatic
 * disabled -fmodules in xcode, because of clang 3.4 issues
 * version bump to v0.3.0-d3
