OK. 
I presume that in the case of the stockmarket we only need to
save the token locations, as all other info is available in 
the initialisation XML (item <stockmarket>).

So would the following toString() output be OK for StockChart/StockMarket?

<stockmarket_state>
  <square_state name="G7">
    <market_token company="B&amp;O"/>
    <market_token company="NYC"/>
  </square_state>
  ...
</stockmarket_state>

As shown, we should translate funny characters ('&' becomes '&amp;').
If this the only character to watch it's no problem,
but to solve the general case we would need some existing package.

Erik.
