NE-3. Read/Write from one file to another

Now it's your time to put into practice all the little things you have learned!

Create a txt (or doc file) with some content, some text. Write a script that reads the contents of this file and pastes it into another .txt file.

For now just writing, and NOT appending it's fine. Since we don't want to have a duplicated content.

Try to do this the non-blocking node.js way with promisifying the fs module's functions, and use the core path module to locate the files.
