Notes on serialization:
    Every message sent has a corresponding class, all of which derive from the
base Message class. Each message class has two common function:
 * serialize() - returns a string representation of the class
 * constructor(vector<string>) - deserialization from the string

The socket class has two functions related to messages:
 * sendMessage() - calls serialize and sends the string over the socket
 * getMessage() - splits the incoming text by whitespace and call the correct
constructor; returns null if the message type of the incoming message is unknown

the first field of a serialized message is always the type of the message



Notes on unit tests:
    we used the python-pexpect module to start PCE and router sessions and interact with them.
we included the pexpect-2.3.tar.gz tarball from http://pexpect.sourceforge.net/pexpect-2.3.tar.gz
so that anyone with a UNIX-like system and python could run "make tests"

the Message_test application uses a modified echoserv from:
http://www.paulgriffiths.net/program/c/srcs/echoserv.tar.gz

These files are strictly for our unit tests:
    echoserv.cpp
    local.cfg
    Message_test.cpp
    pexpect-2.3.tar.gz
    message_test.py
    multi_pce_test.py
    single_pce_test.py
    star_pce_test.py
    test_common.py
