Configurators are classes that can manipulate the engine, bootstrapper, and other items at startup.

Configurators are used internally by the bootstrapper and while you generally won't need to use them directly, you can create your own configurators by implementing IConfigurator<TConfigurable> where TConfigurable is a type that implements IConfigurable. The following types currently implement IConfigurable:

• Bootstrapper: the configurator can directly configure the current bootstrapper.
• Engine: the configurator can directly configure the current engine.
• ConfigurableCommands: used to configure the commands.
• ConfigurableConfiguration: used to configure the IConfigurationBuilder that maps configuration files to settings.
• ConfigurableServices: used to configure the IServiceCollection.
• ConfigurableSettings: used to configure settings.

The IConfigurator<TConfigurable> interface contains a single void Configure(TConfigurable configurable) method that provides an instance of the configurable object.

Because the bootstrapper automatically registers all implementations of IConfigurator<Bootstrapper> and IConfigurator<IBootstrapper>, those types of configurators can be particularly helpful in extension scenarios where you have an library that should operate on whatever bootstrapper loads it.
