- * \author Victor Julien <victor@inliniac.net>
- *
- * Implements per host bits. Actually, not a bit,
- * but called that way because of Snort's flowbits.
- * It's a binary storage.
- *
- * \todo move away from a linked list implementation
- * \todo use different datatypes, such as string, int, etc.
