   \class Categories categories.h
   \brief The Categories class is a database that groups categories and maps ids to names.
 
   The Categories class is the low level Categories accessor class. To
   add a category menu and filter for your application, see CategoryMenu.
 
   The Categories class allows the developer to add, remove, and rename
   categories. Categories can be created for an individual application
   such as Todo List or to be used for all applications. Categories
   that can be used by all applications are called global
   categories. Each PalmtopRecord subclass stores categories as an
   QArray<int> using PalmtopRecord::setCategories() and
   PalmtopRecord::categories(). This allows each record to be assigned
   to multiple categories. This also allows the user to rename a
   category and for it to update automatically in all records.
 
   This class provides several methods to convert between a category id
   and it's associated string such as id(), ids(), label() and labels(). A
   helper class called CategoryGroup is used to access categories of a
   single application group, such as Todo List. Global categories can
   also be accessed via CategoryGroup objects.  See appGroupMap() and
   globalGroup() for the appropriate accessor methods.
 
   Categories are stored in an xml file in the Settings directory
   (Categories.xml). A global function called categoryFileName() will
   return to appropriate QString file location to be passed to load()
   and save() for the master categories database.
