/** A category manager used to manipulate the categories held by the Calendar store. 

There are 12 built-in category types which are specified by CCalCategory::TCalCategoryType. 
In addition, clients can create as many of their own categories as they like by giving a name to the category.
This class is used along with the class CCalCategory to manipulate the categories in the file, for instance to 
add, delete and get a list of entries filtered by their category.
