Take a line from a crontab and find out when events will occur

Given a line from a crontab, tells you the time at which cron will next run the line, or when the last event occurred, relative to any date you choose. The object keeps that reference date internally, and updates it when you call nextEvent or previousEvent - such that successive calls will give you a sequence of events going forward, or backwards, in time.

Use setCounterToNow to reset this reference time to the current date on your system, or use setCounterToDate to set the reference to any arbitrary time, or resetCounter to take the object back to the date you constructed it with.

This module uses SetCrontab to understand the date specification, so we should be able to handle all forms of cron entries.
