Detailed Description

Author: Victor Julien victo.nosp@m.r@in.nosp@m.linia.nosp@m.c.ne.nosp@m.t

Implements per flow 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

use different datatypes, such as string, int, etc.

have more than one instance of the same var, and be able to match on a specific one, or one all at a time. So if a certain capture matches multiple times, we can operate on all of them.
