general flow

• the models store the structure of data used throughout the project
• the controllers directly interact with the database files, using locking to ensure the files are not modified unexpectedly
• the server births a new thread for each incoming connection
• the client must login using credentials which are verified by the worker thread using functions provided by the user controller
• if the same user logs in from a different terminal, the previous thread with for that user account is cancelled
• once authenticated, the server responds with the role of the user
• the client shows the menu corresponding to the role of the logged-in user
• subsequent requests are serviced as they arrive and the response is sent by the worker thread through the socket
• for special kinds of request where the size of the response is not pre-known, the data is buffered into the socket the number of objects to be read from the socket is sent in the response under the bufcount variable
• the types of requests and their required data can be seen in Request.h
• unions are used in the Request and Response structs to store the required data before being sent
