A retry fn has been added to retry any failure a given number of times (say a package err) and a proper error handling has been added to check for the mechanism (test-error-handling.js)

Ex- If node and npm installed versions are lower than the one mentioned inside utils.js, an error will be thrown at the end inside the terminal (errors.push(err.message))
