Example extension for development

In order to make extensions development easier and much clear, i have attached an example extension that you can use to develop your own extensions.
It contains very clear examples on how to:
– make the extension available only for certain apps: customer / frontend / backend / api / console
– hook in one/more of the above apps
– hook into existing actions / hooks
– add your own settings page
– add a simple menu link
– load your own controllers
– override mailwizz controllers with yours
– add a simple landing page
And more. It is also very very well commented so that it is very clear how everything works.
