Make a copy of .env.template and name the new file as .env. The .env file
controls the following:

Run index.js using Node.js:
node index.js
A CSV file is produced at the location as specified in LOG_FILE. The CSV file
contains the following columns:
- The date of bandwidth usage collection, in the format
YYYY-MM-DD. - The number of incoming bytes.
- The number of outgoing bytes.
- The total number of I/O bytes.
For example:
2015-10-31,18974025324,34145831737,53119857061
In case of errors, the error message is written to stderr.
