Install flow tool for static analysis

[akobaidan]

Static analysis tool Flow is installed in the codebase through the command npm install --save-dev flow-bin. To configure the Node.js codebase to use the tool, a Flow script is added in package.json. The tool was then initialized through the command npm run flow init. This created a .flowconfig file that defines the tool's configuration to work correctly within the codebase. Additionally, the command npm run flow was deployed to launch the Flow server and confirm that no errors were found in the codebase.

The following screenshot of the terminal shows the output of running npm run flow init and executing npm run flow.

I have incorporated the changes made, installed the tool, and ran it. The output on my machine matches the one here. LGTM!

The tool installation looks good and functions as it should.
