+  \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.
