Ideas for improving the database seeding script

[jhsu802701]

Which ones should I put into a pull request? My ideas:

1. There is no progress bar for adding the 198 sessions. Instead of showing a progress bar for each individual session (which takes only a few seconds at most), why not instead show a progress bar for the 198 sessions to be added? Out of all the tasks in the database seeding script, adding the 198 sessions takes the longest by far.
2. The number of sessions to be added is the product of the number of rooms and number of time slots. The 198 sessions take a long time. To save time, can we cut back on the number of rooms and/or number of time slots?
3. Add a participant with a non-random name. I'd like to have a user with a non-random name so that I don't have to look through the database to see what email I can use for logging in.
