Changed wording

to reflect that only closed experiments can be deleted
Added bulk reminders page

This is used to send reminder emails to all of tomorrow’s participants
in one click.
Made $new_hash_method a global parameter
Uncommented email lines

Emails will now be sent
Added getDate() method

This returns the subjects scheduled for a given date
Index return array on a separate line

Apparently, this doesn’t work in earlier versions of PHP
Updated the method for checking parameter existence

since extractElement() can’t tell you whether or not a parameter exists
in the file, only whether or not it’s empty.
Check password only if valid username
Fixed typo bug
