Fix Issue Number: 24 - Git Siblings

[tanmaysharma2001]

Fix for the Issue Number 24 in the Cam Repo.

Problem Description: For each .java class, let's count the number of other .java classes which it was updated together with, in the Git history.

Solution Description:

• Use the git log command with --name-only and --pretty=format: options to list committed files per commit.
• Filter the output for .java files.
• For each .java file, track the commits it appears in.
• Calculate the number of times each .java file is committed with other .java files.
• Output the result for each file, showing its "siblings".

@tanmaysharma2001 looks like a very good start, thanks! Now, please, try to run make clean install and then make test lint, in order to check that the code doesn't break anything. Then, please, create a unit test for this script, similar to the tests we already have for other scripts.

Also, if it's a "step", we should name it like all other steps: XXX-name.sh, where XXX is a number.

Hi @yegor256 thanks a lot. I have fixed one the 1 test where my script was failing. Although, i had few problems with installing make clean install, which includes installing dependencies. I'm working on that. Meanwhile I request you to approve the PR so that it can run the tests again. Also i have written the unit test for the script too.

Also I wanted to ask about the step number. I didn't quite understand where should i name it cause other steps are named according to their purposes. For example: aggregate-join.sh.

Sorry if i misunderstood anything. Thanks.

@tanmaysharma2001 this should be a metric, not a "step". Put your file into the metrics/ directory and that's it.

Done @yegor256 Thanks a lot.
