Building on OSX

I can get it to build on Linux but OSX gives:

I think the issue is that std::vector<T>::iterator is not guaranteed to have a constructor that accepts a pointer by the C++ standard. I changed this to use the default constructor in e433ee63e542551a7c6d35ec2d71192fd5a06d62 and it now works for me on El Capitan.

Also, note that this is an unofficial fork of the version of the APPL toolkit released by NUS.
