C++, getting many "undefined reference to..." errors

I've looked around for previous questions to no avail. I'm new to C++ and this may be just a headers issue, but right now building my project I get entire files of methods which utilize a certain type (vector<vector<Point>>) as undefined. In the debugger it says there is an allocator as part of the type, I was wondering if this is normal and fine or part of the problem? All my code can be found at http://ift.tt/1jRSyWc.
