// * Provides convenient access to existing clients for specific Mt Wilson

// * feature-specific clients before returning them.

// * Using this class is not necessary - you can instantiate a feature-specific
// * client, configure it, and use it independently of any other client.
// * 
// * Subclass to add convenience methods for obtaining client instances for 
// * specific features.
// * 
// * Feature-specific clients may look for a feature-specific base URL (for 
// * example if the feature is hosted on a separate server than other features)
// * but should use mtwilson.api.url as the default is there is no feature-
// * specific pom.xml.
