Complete the Exercise

index.js contains starter code that almost entirely works. There are three tasks for you to complete:

1. Process User Input: Create an array containing all of (and only!) the command line arguments passed by the user
2. Generate the userConfig object: Convert the array of user arguments (all strings) into a config object describing the new cowsay
3. Write the cowsay to a file: Using the constant COWSAID_DIRNAME and the config option .file, write the generated cowsay to the user's file system
