PURPOSE
This script is a basic API to expire a membership in AMember. It will look up an AMember account
based on AMember ID, or email, or first and last name. It will then set the expired date for a
subscription to a date in the past. The effectively cancels the subscription, but it keeps
all of the data intact in the database. This script does nothing to cancel payments, it just expires
the subscription.

(see advanced use section)
