[HACKERS] GSoC 2017 weekly progress reports (week 2)

During this week, I mostly worked on testing to verify my code and on debugging to solve some issues I was having. I have specifically created two tests. The first test is about verifying serialization failure when there is a read-write conflict. The second one is about checking false positives. We need to make sure that it doesn't generate false positive serialization failures.  So far, I have got expected results. Any feedback on results will be appreciated.
