type ClassConfigurator 

type ClassConfigurator interface {

	// PropertyConfigDefaults provides the defaults for a per-property module
	// config. The module provider will merge the props into the user-specified
	// config with the user-provided values taking precedence. The property's
	// dataType MAY be taken into consideration when deciding defaults.

	// user specified an invalid dataType, as some validation only occurs after
	// defaults are set.

	// another module. The specified ClassConfig can be used to easily retrieve
	// the config specific for the module. For example, a module could iterate
	// over class.Properties and call classConfig.Property(prop.Name) to validate
	// the per-property config. A module MUST NOT extract another module's config
