sniff class don't create the pcap file

[sebastianhenaosanta]

hey, i've working with this library during a few months, specifically with sniff module. It work very good for what i'm doing but the new version of the library don't create the pcap file. For that reason i installed version 0.2.3 and all worked perfect. i would be good if this version would create the pcap file,while it's sniffing packages.
