CGE should: * Have a `default_parameters.json` file that stores all the default parameter values (which are currently hardcoded into `calibrate.py`). * Have a parameters class that does parameter validation and updating, consistent with PSL criteria. * Use `ParamTools` to deal with the above (and make compatible with [COMP](https://comp-org.github.io/comp-ce/)).
