Automatically download csv file from web site

I need a script that runs daily and does the following: 1. Navigates to [login to view URL] 2. Logs in (if not already logged in) 3. Goes to the "My Lineups" tab 4. Click the Create New Lineup button in the top right 5. For each radio button (i.e. NBA, CFB, CBB, etc.): a. Click each available sub-button for available contest start times (i.e. 11/12 7:00pm 9 games, 11/12 9:00pm 2 games, etc.) b. Click the continue button c. Click the "Export to CSV" button d. Save the file with the following name format: "<sport>_YYYY-mm-DD_<num_games>". So in the example where it's an NBA contest on November 12, 2014 with 9 games, the csv file would be saved with the name "NBA_2014-11-12_9" The end result would be that every day, this script would run and it would download all of the CSV files that are posted on Draftkings.
