Peer review

1. The code follows the original repo structure and you get the correct output.
2. The kernal code preserves all registers except $k0 and $k1.
3. The program does not seem to reach a kernel loop after overflow but i may have made a mistake somewhere.
4. The bits of the status register is in user mode" and interrupt enabled
5. The code is well commented and explains implementations. Overall a good job.
