/**
* Class for easy access to categories in VCARD, VEVENT, VTODO and VJOURNAL.
* A Category can be e.g. 'Family', 'Work', 'Chore', 'Special Occation' or anything else
* that is either parsed from a vobject or that the user chooses to add.
* Category names are not case-sensitive, but will be saved with the case they are
* entered in. If a user already has a category 'family' for an app, and tries to add
* a category named 'Family' it will be silently ignored.
* NOTE: There is a limitation in that the the configvalue field in the preferences table is a varchar(255).
