Module with own route site

Hello,

i want to create a module, to present data on a special site.
For Example, for a rest service or a simple landingpage.

For this, I have to register a new controller for index.php.
I tried it, but I can't register the controller with the module.

My GitRepository: https://github.com/SpeedRunner/oxidtest
Objective: http://myshop.com/index.php?cl=oxidtest

It work's, when I copy the oxidtest.php in the application/controllers-Folder.

Can somebody help me?

Thanks
Peter
