Detailed Description

Category objects are immutable, strictly speaking.

If you call methods that change the database, like to refresh link counts, the objects will be appropriately reinitialized. Member variables are lazy-initialized.

Todo:: Move some stuff from CategoryPage.php to here, and use that.
