 Export Memrise course words to CSV (technically TSV, or "tab separated file", but it is effectively the same).

 1. Log into Memrise.
 2. Navigate to the course page you would like to export (e.g. https://app.memrise.com/course/2156672/german-random-01/).
 3. Open the browser's Developer Console (https://support.airtable.com/hc/en-us/articles/232313848-How-to-open-the-developer-console)
 4. Paste the below script into the console and hit enter.
 5. After all pages have been loaded, copy and paste the final word list into spreadsheet.
