Changed the test into testing the USART. The CAN testing functionality is commented away but can easily be uncommented.
By the way, I tested the USART on hardware and it WORKED! :)
Merge branch 'master' of https://github.com/naiad-auv/naiad-auv-software
Added a draft project for making the BeagleBone Black communicate with the CAN-link.
Some changes done to CAN-link when testing. Tests are unsuccessful at the time.
