/**
 * Contains shared logic for applying key-value pairs and CSV strings
 * to specific settings in CodegenConfigurator.
 *
 * 
 *     This class exists to facilitate testing. These methods could be applied
 *     to CodegenConfigurator, but this complicates things when mocking CodegenConfigurator.
 * 
 * 
 *     The methods named {@code apply...Kvp} take a string of comma-separated key-value pairs.
 *     The methods named {@code apply...KvpList} take a list of such strings.
 *     The method named {@code apply...Csv} takes a string of comma-separated values.
 *     The method named {@code apply...CsvList} takes a list of such strings.
 * 
 * 
 *     The corresponding {@code add...} method on the passed configurator is called for each key-value pair (or value).
 *
