These might change the layout of the rendered markdown files. This will
also fix some typos along the way:-)

 This class will have the following public member functions:
 
- - A default constructor and a destructor.
- - A `show` function, which will show the component on the screen. Note that in order to render

- - A `hide` function, which de-registers the component from the windowing system.
- - A `run` convenience function, which will show the component and starts the event loop.
- - for each properties:
-    * A getter `get_<property_name>` returning the property type.
-    * A setter `set_<property_name>` taking the new value of the property by const reference
- - for each callbacks:
-    * `invoke_<callback_name>` function which takes the callback argument as parameter and call the callback.
