// PCAP is a standard file format for network capture files. This also extends
// to any capture of packetized intercommunication data. This file provides a
// class called PCAP which is a very light wrapper around the file format,
// allowing only creating a new PCAP capture file and appending packets to it.
//
// Example use:
// PCAP pcap(new IOFile("test.pcap", "wb"));
// pcap.AddPacket(pkt); // pkt is automatically casted to u8*
