Removes duplicates from a list of emails, URLs, IDs or anything else one per line, and tells you how many went.
Comparison can ignore capitals and surrounding spaces, so "Aisha@Example.com" and " aisha@example.com " count as the same entry. You choose whether the first or the last occurrence survives.
