• Got magician working with new platform
• Export Honda API. Increase dealer code field size from 5 to 10, incase it is relevant for new dealer codes
• Export Honda API.  Log low level API comms in event of a failure. At the moment it fails but doesn't log comms so no idea what root cause of failure is

• Beginnings of some changes to support doing workshop service reception via a web based tablet. This version of c9 acks the submitted tablet data entry but throws the data away doing nothing useful with it.
