Mock version of LabJackInterface.

This mock monitors what data is written to the LabJack and adjusts what data is read to be what we expect from the real lamp controller.

Parameters:

• An IP address if connection_type=TCP

• A serial number if connection_type = USB

• For testing in an environment with only one LabJack you may use ANY.
