Overview of program design:

The design of our program is consistent with the lab specifications.  The
player and dealer take turns sending data to eachother in buffers. In our
eyes, there were two major design decisions to be made.  The first decision was
how to store and organize player and game data on the dealer side.  We chose
to have the dealer class hold two maps, each keyed by strings.  The first map
hold pointers to dynamically allocated Player objects, the second map holds
pointers to dynamically allocated Game objects.  This allows us to look up a
specific game or player in constant time.  Furthermore, looking ahead to future
labs, we can solve the issue of having players with the same name simply by
assigning each player a unique ID and using it to key into the map.  The second
major design decision was how to send the list of games.  We opted to list
the games as null terminated strings, with an empty string signaling the
end of the list.  That is, the list ends when two consecutive 0 values are
read.

Wrapper Facades:

The wrapper facades we used were ACE_INET_Addr, ACE_SOCK_Acceptor,
ACE_SOCK_Connector, and ACE_SOCK_Stream.  We implemented our own command line
parsing mechanism.  The ACE_SOCK_Acceptor was helpful in making it easy to
accept connections from our server and initiate them with a connector from the
client.  We knew we needed to maintain multiple connections, so we stored a
ACE_SOCK_Stream object within each player.

Instructions:

1. Unpack the files with "unzip cse532-lab0".  No arguments are necessary.
2. Build both the client and server programs with a simple "make".
3. Run the program using the command line arguments specified in the lab.  The
client executable is "./client" and the server executable is "./server".
4. The output files from our significant test can be found in the
"output-files" directory.  The test used multiple clients and multiple
computers.
