Calendar categories can be associated with a calendar entry.

There are 12 built in category types defined by TCalCategoryType. Additionally, it is possible to define extended category types which are held as a descriptor of any length.

Any number of categories can be specified for an entry. CCalEntry provides member functions for adding, deleting and fetching categories for an entry.

CCalCategoryManager functions enable the client to add\delete\fetch categories from a Calendar session and to get a list of entries filtered by their category.
