Updated Business Export and Import request and response formats to version 19, with the following changes:
- Renamed "vehicle" to "unit" throughout the API and this documentation to reflect the renaming of our "Vehicle Sales" module to "Unit Sales". All functionality remains unchanged.
- This affects the following elements:
- Business Export: vehicles -> units, vehicle-types -> unit-types, new-vehicles -> new-units.
- Business Export CSV format: field vehicle-code -> unit-code, heading Vehicle Code -> Unit Code, heading Vehicle Type -> Unit Type.
- Business Import: vehicle -> unit.
