+ * The common interface definiton that plugin classes can use to inherit from
+ * when defining their own options interface for their constructors.
+ *
+ * Not all plugins need to have a unique plugin ID, so if the plugin you are
+ * working does not, it is okay to provide a dummy implementation, but it is
+ * not really recommended. Instead the constructor of your plugin should
+ * generate one automatically at runtime if you definitely do not want the
+ * caller of your plugin class to have to provide an instanceID.
+ *
+ * For example if you have a ledger called `FooBar` then this could be seen as
+ * a recommended implementation:
+ *
+ * ```typescript
+ *
+ * interface IPluginLedgerConnectorFooBarOptions extends ICactusPluginOptions {
+ *   logLevel?: LogLevelDesc;
+ *   // your other FooBar specific parameters here
+ * }
+ *
+ * class PluginLedgerConnectorFooBar implements ICactusPlugin {
+ *   constructor(public readonly options: IPluginLedgerConnectorFooBarOptions) {
+ *     // your constructor logic here
+ *   }
+ *
+ *   public getInstanceId(): string {
+ *     // this works because your {IPluginLedgerConnectorFooBarOptions}
+ *     // inherits from the ICactusPluginOptions interface.
+ *     return this.options.instanceId;
+ *   }
+ * ```
