A Category sets the primary topic or subject for Category Locations used for storing, organising, and finding Entries
Categories can be reused in multiple Locations. For example, a Category may describe a Company. That Company (adjective) produces two types of product, Cars and Motorcycles (noun). That Category could therefore be used for a Location for that company under Cars in the heirarchy, and also for another Location elsewhere under Motorcycles.
Categories are only used by Locations.
Categories can currently be added by Suggea Users, when creating a new Location which is not reusing an existing Category.
