No currency units are present in the default unit data set

Description

The properties cost, costWithMargin and costMargin of the Cost Conceptexcept a dimensionless unit. By default no currency unit is available in VirSat. In the picture below I added Euro (€) as a dimensionless unit.

As a possible problem I see, that different currencies are needed. But the exchange rates between currencies are not fixed and can fluctuate a lot. Maybe this is this reason why no currency has been created?

The problem I see, when no currency exists, is that you do not know if e.g. Euro or Cents are meant.
