/** Two phase constructor for the calendar iterator.

This class can be used to find all the calendar file names

known by the calendar. 

If calendar info has been set on the file then the CCalCalendarInfo

will be valid and other properties on the CCalCalendarInfo class

would have been set.

The iterator is a snap shot of the files that exist when the iterator

is created. If a file is created or deleted after the iterator was

created then the iterator will be invlid and should be recreated.
