map work

[esaule]

There is a lot to do in the support of maps in the C++ client
(we'll eventually port those to the other languages)

1. The state and county object have getter functions but not setter functions
2. The getter functions should be const
3. The colors in the objects should be Bridges Color object and not string
4. The datasource object should support importing all the states at once
5. The datasource object should support importing the states but not the counties

Done with 1, 2 and 3 above, but JSON creation code is not updated for the r,g,b colors yet.

I think at this point the only thing we miss is documentation.
