Class: SwiftTypedPacketReader

Description:
This class reads packets from an istream. The type of each packet is determined by examining the packet's APID, and the packets of different types are routed to different output PacketPipes.

Typical usage would be to create a SwiftTypedPacketReader object, then call the head2(), head3(), uvot(), and ldp() methods to connect the "outlet pipes" to the desired processing plumbing, and then call the pump() method to make everything go.

Instead of calling pump(), you may pull packets from any of the outlet pipes. This causes packets to be read and distributed to the appropriate pipes until a packet comes out of the pipe from which you are pulling.

LDP packets will be of the appropriate type (plain or with checksum) but all LDP packets go to the same output drain.
