Can now load and run a network

- The library is now capable of loading the test session and running
   it successfully.

 - Updated the example application, which is really the same as the test
   and should probably be deleted.

 - TODO: The input names actually *do* need to match the names when the
   network was created. The hardcoded names in onnxruntime_wrapper.c
   will *not* do!
