Initial commit

Adds unit tests to project, needs to be updated

Removes unit test from project and changed path of include

Unit test page should instead point to where we expect the unit test to be
cloned in our main project. In this case we expect all our includes to be located in
a common root directory

Removed git modules since submodues are no longer needed
