Backend TODO

[LuxMiranda]

• Write the marshalling/unmarshalling to not require elevated privileges (i.e., don't change read-only memory)
• Get a localHello/localAck dialogue working
• Remove every instance of typedef Com. It's a little too vague, especially with multiple definitions across the projcet.

[AmmonHepworth]

• Add a confirmation (cout or unit test) that the acknowledge was sent/recieved.
  Do something with the acknowledge or failure
• Add messageCallback to components
• Make messageCallback respond to messages (maybe calling receiveMessage)
