Connector unit when exporting FMU

[larsviktorlarsson]

When one exports an FMU and selects quantity, the unit in the exported FMU is automatically set to the SI unit value, even if the unit is changed with the drop down menu under "default Value".

I guess this is tricky to solve, as I know Hopsan always use SI units in calculations and that unit scaling is used in the plots only.

However, in the case where the FMU is connected to another FMU with non-SI unit, it should be possible to set the unit to a non-SI unit.

E.g:

The user selects an output and chooses "Pressure" as quantity. The unit "bar" is selected in the drop-down menu at "default value". "bar" is then written as "unit" attribute of the output in the modelDescription file of the exported FMU.
