To fit into the generic way that the new Field class updates itself:
via the toString() method of any ModelObject subclass.

No, Price embeds a StockSpace, Cash embeds an int.
I could probably find a way to merge these classes,
by representing price by an int as well as a StockSpace.
But that would require extra update code in PublicCompany,
so it does not really reduce complexity to me.

Anyway, this is kind of an experiment on how to do these things,
so it is of course well possible that we find ways to simplify this later.
