Message has been revamped to handle data and get it for askers, the mailbox will be used to ship messages between services and users.

Using the 2 chip select lines we now have a object that can handle all the SPI communication at a low level.

Features added :
 - write safety features
 - read safety features

The purpose of message object is to create a unified way of communicating on both sides of the bluetooth connection.

Included is code for some simplistic test functions that allow server communication.

File structure has been changed for the final time. Research is nearly completed on the usability of our code by students. The goal is to ensure the code is easy to import and quick to start working with.
