Hi all!

There is a new subfilter module. It uses fast Wu-Manber algorithm for  
multi-pattern search. Probably it would be interesting to someone:

It is possible to add regular expressions support if it is required, but  
as  
a separate engine (i.e. use libpcre instead of builtin Wu-Manber). The  
combination of them is a good challenge.

The code may still have bugs, since I don’t still have a time to write  
good  
tests.

Thanks
