We often have to request changes to PRs due to tests not being present or an entry to the readme isn't added.

I suggest we create a unit test that:
1- reads all the problem names and asserts there is a file for testing. We can do that by inspecting the problem's name and asserting there is a corresponding ${file_name}_test name with assert_ methods.
1- Reads the README and asserts there is a link to the problem created. This one is less important than the previous one.

Thoughts @hot9cups ?
