Experimental/parameter parsing

[andrewbaxter439]

What

• Adds a startup element to SimPathsMultiRun which reads parameter configs from config file
• Allows some of these to be amended

Why

• Changing parameters between runs could be done quickly with config files, rather than rebuilding the model
• This would allow script-based runs of subsequent models with tweaked parameters

[Copilot]

Pull Request Overview

This PR adds configuration-based parameter parsing to SimPathsMultiRun, allowing model parameters to be dynamically updated from a config file without rebuilding the model.

• Introduces a new static map (parameterArgs) to store parameter configurations.
• Updates the YAML config parser to extract "parameter_args" and calls an overloaded updateParameters method.
• Alters the Parameters class by removing the final modifier from some fields to allow dynamic updates.

• [nitpick] Consider renaming the method parameter 'parameter_args' to 'parameterArgs' to maintain consistency with the field naming and common Java conventions.

public static void updateParameters(Map<String, Object> parameter_args) {

src/main/java/simpaths/data/Parameters.java:266

• [nitpick] Since the final modifier was removed from fields like MIN_START_YEAR, MAX_START_YEAR, and BASE_PRICE_YEAR to allow dynamic updates, consider renaming them using camelCase (e.g., minStartYear) to clarify that these values are mutable.

private static int MIN_START_YEAR = 2011; //Minimum allowed starting point. Should correspond to the oldest initial population.
