Ultimately the purpose of the exercise is to either shuffle the 4 
events (3 currently in the 2 calendars, 1 in the new invitation) into 4 
fitting events in the 2 calendars, or conclusively fail (there's no way 
this fits).

Using the example documented in the aforementioned article, this means 
that for an invitation Tue-Wed to resource collection "car", the 
following steps precede successful resolution:

- Obtain all events that overlap with the slice of time we're 
attempting to make a reservation for, i.e.;

   - The Car #1 Wed reservation,
   - The Car #2 Mon-Tue reservation,

- Obtain all events that overlap with the events obtained in the 
previous step, i.e.;

   - The Car #1 Mon reservation,

- Insert into the pool the Tue-Wed reservation,

- Shuffle reservations around between resources in the pool until 
everything fits with no conflicts.

Wallace will need virtually all the details on which properties for 
which events would need to change, in order to make the necessary 
changes in the IMAP Calendar folders and as subsequent iTip messages may 
need to be sent out.

Kind regards,
