[abagali1]

Description

Write a Driver class for the Iridium hardware radio for all interfacing operations between the Pi the Iridium radio.

Specifications

The new driver should be placed in MainControlLoop/lib/drivers/Iridium.py, the class name should be Iridium

The specifications are kind of vague but there are two required functions: read(), write(msg)
The read function should read from the Iridium radio and return a single byte
The write function should take a string and send it through the Iridium radio,
there should not be any formatting of the message in this method

As always, ensure you are following the Iridium documentation exactly. The documentation can either be found online through Google or on the TJREVERB Google Drive account
