Bulk Email to ID Converter

I wrote this program to convert a large amount of Email addresses (since those are most easily obtained from the end-user). It helps immensely when there are 300+ users in a site. If you get a "<-- NOT FOUND" next to a result, they might have given you a login ID or email address (you didn't enter the right criteria). This will still return their kerberos login even if they're having their Mail ID redirected.
