Decide and inform user about units for data import mW/nm or W/nm

[DieterLa]

The input assumes the data given in W/nm
Results are shown in mW/nm
This is not consistent
Best option would be allowing the user to decide about his data.
second best option is to inform the user about the required scaling in W/nm
Often data is saved in mW/nm

[JZauner]

Actually, the second sentence in the import/Upload section states that data needs to be in W/(m² * nm), so the second best option is already included.
Rescaling can be easily done in the Import Options. I think the easiest way to implement your best option would be to just make a little selection available there to state how the data is scaled. I can do that.

[JZauner]

I have added an option to set the import format to mW, to W, or to your own scale. It will go online in Version 1.0.0 of Spectran
