/**
   @file   icaldirset.h
   @brief  icaldirset manages a database of ical components and offers
  interfaces for reading, writing and searching for components.
  icaldirset groups components in to clusters based on their DTSTAMP
  time -- all components that start in the same month are grouped
  together in a single file. All files in a sotre are kept in a single
  directory.
  The primary interfaces are icaldirset__get_first_component and
  icaldirset_get_next_component. These routine iterate through all of
  the components in the store, subject to the current gauge. A gauge
  is an icalcomponent that is tested against other components for a
  match. If a gauge has been set with icaldirset_select,
  icaldirset_first and icaldirset_next will only return components
  that match the gauge.
  The Store generated UIDs for all objects that are stored if they do
  not already have a UID. The UID is the name of the cluster (month &
  year as MMYYYY) plus a unique serial number. The serial number is
  stored as a property of the cluster.
