+/** A handle to the calendar file.
+
+When the client instantiates a CCalSession, it will connect to the calendar server. 
+In turn, the client can use its APIs, for instance to create or open a calendar file.
+
+The agenda data in the file can be accessed as entries. To access the entries, clients should
+use class CCalEntryView or CCalInstanceView to process the entry data. However, both view classes 
+require the handle to the file which is represented by this class.
+
+A calendar file can be opened on any writable drive. Note that if the file is opened 
+on a removable media and that media is removed, operations will leave with KErrNotReady.
+This error can also happen when trying to access file attachments on removed media.
+When this error occurs, the user should close the CCalSession and re-open it once the media 
+has been replaced. 
+It is recommended that when using a calendar file on removable media, the user should watch for when 
+the media is removed / replaced using the RFs::NotifyChange API.
+
+The session object must not be destroyed until all the objects which where created by referencing it 
+have been destroyed.
