/** Library for Homebridge plugins.
  * see the {@tutorial homebridge-lib} tutorial.
  *
  * Homebridge Lib provides:
  * - A series of base classes for building Homebridge dynamic platform plugins:
  * {@link Platform},
  * {@link AccessoryDelegate},
  * {@link ServiceDelegate}, and
  * {@link CharacteristicDelegate}.
  * - An abstract base class to building command-line tools:
  * {@link CommandLineTool}.
  * - A series of helper classes for building homebridge plugins (of any type)
  * and/or command-line utilities:
  * {@link AdaptiveLighting},
  * {@link Colour},
  * {@link CommandLineParser},
  * {@link CustomHomeKitTypes},
  * {@link Delegate},
  * {@link EveHomeKitTypes},
  * {@link HttpClient},
  * {@link JsonFormatter},
  * {@link MyHomeKitTypes},
  * {@link OptionParser},
  * {@link PropertyDelegate},
  * {@link SystemInfo},
  * {@link UiServer}, and
  * {@link UpnpClient}.
  *
  * To access the classes provided by Homebridge Lib from your module,
  * simply load it by:
  * ```javascript
  * import { Class } from 'homebridge-lib/Class'
  * ```
  *
  * Note that each class provided by Homebridge Lib is implemented as a
  * separate Javascript module, that is loaded lazily on first use.
  * Due to the way NodeJS deals with circular module dependencies, these modules
  * might not yet be initialised while your module is loading.
