a representation of a string containing Policy parameter data
This class facilitates reading data from a string. This class is especially useful for supporting string I/O from Python. The data is encoded in a supported format (just like the contents of a policy file).

Return a (newly allocated) std::vector of active Citizens sorted by ID.
You are responsible for deleting it; or you can say std::unique_ptr<std::vector<Citizen const*> const> leaks(Citizen::census()); and not bother (that becomes std::unique_ptr in C++11)

This may cause the first few records of the source to be read. In this implementation, once the format is definitely determined, the format name is cached internally, preventing re-determination on the next call to this function.
