[boost] A grep like boost::iostreams filter.

Hi folks,

I tried to use the regex_filter for grep like functionality, but I think it
doesn't work like that. So, here goes a grep_filter and a driver main()
function as an example. It is an input filter which returns only the
matching lines of the given regex.

I think it can be used by others, too. Is it possible to put this class into
distribution, as an example maybe?

Thanks,
