returns true if an event has already occurred before a date
<p>
If QL_TODAYS_PAYMENT is true, then a payment event has not occurred if the input date is the same as the event date, and so includeToday should be defaulted to true.<p>
This should be the only place in the code that is affected directly by QL_TODAYS_PAYMENT
