C++ A* Search

C++ implementation of an algorithm capable of more efficiently finding paths through a more complicated maze.

We can not use any library besides iostream and using namespace std is frowned upon.  All work must be done in the a-star.hpp using our custom string library using the string.cpp/hpp files.  all the instructions are in the .png file and more are in the a-star.hpp file.  the more comments the better.  a-star-test.cpp is used as test to see if a-star.hpp works.
