Hi Fellow UTers

I have a class library called abizness. My friend took a copy of abizness and used it for a while. While my friend was using the class library I continued to modify and add classes to the library. My friend made some nice changes to 2 of the classes that I had not modified. My friend also added 2 classes to the library.

The Question:
How do I get the 2 classes that my friend modified and the 2 new classes that my friend added back into my abizness?
