Create one input payload that hangs the program (Infinite Loop)
Write Bug.txt to explain the bugs triggered by each of the payloads
Fix the bugs and perform regression tests using Travis

Coverage and Fuzzing (Part 3)

Use lcov to perform a coverage test and see how much of the program is covered
Create testcases to increase coverage by two more lines
Fuzz the program using AFL
Use passing test cases generated by AFL to improve coverage of the program
Fix two fuzzer generated tests that crash the program
Perform regression tests using Travis CI
Brief write up explaining the above bugs that crashed the program
