 Simple logging module, that supports terminal coloring and different plugins

 There are different Logging levels, that also apply terminal coloring:
 
-``` javascript
-Logging.debug("Debug message")
-Logging.log("Log message")
-Logging.warning("Warning")
-Logging.error(new Error("To less creativity"))
-Logging.error("Just an simple message as error")
-Logging.errorMessage("Nearly the same as error")
+```javascript

+Logging.log("Log message");
+Logging.warning("Warning");
+Logging.error(new Error("To less creativity"));
+Logging.error("Just an simple message as error");
+Logging.errorMessage("Nearly the same as error");
 ```
 
-All Logging types except the simple error take as many arguments as you want. These will be joined with spaces and serialized with the node util.inspect function.

 There is a Plugin API available, that makes is possible to add custom Logging Adapter.
 
-``` javascript
+```javascript
 const Demo = new LoggingBase("Demo");
 Demo.addAdapter(new DemoAdapter({ color: "rainbow" }));
 ```
 
 The adapters need to provide a very simple Interface:
 
-``` typescript
+```typescript
 interface Adapter {
-    init(observable: ObservableInterface<Message>, name?: string): void | Promise<void>;
+   init(): void | Promise<void>;
 
-    flush(sync: true): void;
-    flush(sync: false): void | Promise<void>;
+   onMessage(message: Message): void;
+
+   flush(sync: true): void;
+   flush(sync: false): void | Promise<void>;
 }
 
 interface Message {
-    type: LoggingTypes;
-    name?:string;
-    text: {
-    	raw: string[],
-    	formatted: string[]
-    };
-    date: Date;
-    file: string;
+   type: LoggingTypes;
+   names?: string[];
+   text: IFormatted;
+   date: Date;
+   file: string;
+}
+
+export interface IFormatted {
+   color?: IColors;
+   bgcolor?: IColors;
+   bold?: boolean;
+   italic?: boolean;
+   blink?: boolean;

+   content: string;
 }
 
 enum LoggingTypes {
    Log,
    Warning,
    Error,
-   Debug
+   Debug,
 }
 ```
 
-The `ObservableInterface` comes from `@hibas123/utils`. It provides a very simple api for subscribing and unsubscribing from the message events.
