dpkt is a great packet decoding library that is poorly documented and has few 
examples. In this project, I propose that we document dpkt. For each
protocol, there is a set of functions. Each function needs to be documented.
We will also create sample packet captures and software that decodes the sample
packet captures.
Each protocol is a deliverable. Each function is a deliverable. Each sample
packet capture is a deliverable.
The list of packet captures for testing purposes is given in the file 
test_cases.txt, which is a tab-delimited file giving the file name and test
conditions the file was generated under.
To install dpkt under ubuntu:
sudo apt-get install python-dpkt
sudo apt-get install python-libpcap
