What I need for this exercise is which events (if any) in $imap_folder 
overlap with the [start]-[end] slice of time I'm getting. Recurrence 
rules will need to be included, of course.

A little further on, I may, from a set of folders (resources in a 
collection) within which I may want to re-schedule reservations. See
