Introduction
A Packet is the largest communication object between established peers. All communication is done
via these packets. The packet itself consists of a fixed size header, and a variable size body.
The body contains a more specific type of data.
Packet Header
The packet header has a fixed size of 4 bytes, with the following layout:
0 1 2 3
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

The first byte is used to indicate the version of the protocol. Currently, only version 1 is supported
(0x01). The next byte is used to indicate the type of the body. 0x00 indicates a data packet, while
0x01 indicates a control packet. The remaining 16 bits are currently reserved, and should be set to
all 0.
