    Note that Config is an abstract class because it has 2 pure virtual functions.
    Child classes must add public member variables that store the config data,
    as well as implement writeToJSON and readFromJSON that use pt[key]= value and
    pt.get_or<type>(), respectively, to convert between member variables and the
    property tree. See tests/test_config.cpp for an example.
